These days I run in a gym but I didn't always have access to one. When I did run outside it was usually with headphones on, my phone in an armband, and without carrying pepper spray. I did take safety measures though, like not running in isolated areas where escaping would be difficult and avoiding people walking toward me on the sidewalk or cars parked on the side of the road whenever possible. I would try not to appear tired to potential onlookers (head & shoulders poised) & I avoided running in dawn/dusk hours when visibility was low. I thought I became vigilant after years of running outdoors but despite my efforts I have had a few encounters, the worst happening when I was nearly attacked by a demented person one day as I was crossing a bridge. I didn't have an armband with me that day. One can't be fully prepared every time, and sometimes taking every precaution won't ensure safety.

I am in my late 70s and exercise moderately. Two of my contemporaries were running fanatics and never made it much past 68. Too much strain on the body is unnecessary and at some point becomes less beneficial and maybe even dangerous.

And you learned that from three examples. Great science, no doubt.

Classic weasel word. It's almost mandatory in the current sad state of science.

After a run and/or your next weekend workout, you may enjoy reading, Born to Run by Christopher McDougall. Warning: You may transform into a Tarahumara, if only in spirit. Happy new year!
Howard Levine (Middletown Twp., PA)
I've been jogging/running for about 43 years. (Logged close to 25,000 miles.) There are some other pretty good returns on the time spent running. If you can find a nice area far from noise and air pollution just enjoy the fresh air, enjoy the smell of flowers/trees, listen to the birds, tune in to nature. The 30-45 minutes spent yield "mental" benefits as well. It's amazing how you can clear your head of the demands of the day. Stay within your range Find a safe place to run Sun Screen Comfortable footwear Dress for elements Enjoy
Norman Canter, M.D. (N.Y.C.)
Running is fine, but depends on the integrity of the meniscus cartilages of the knees and absence of low back pain due to arthritis, disc, etc. Race Walking can be as intense as running if proper form is employed and does not need great knees or a great lower back, additionally, since the leg strikes the ground in a straight position, lower quadriceps muscles are better exercised which then protects against knee/cartilage injuries. In the sport, there have been some remarkably aged competitors.

"May" is the key word in this headline and article.

That's called hedging. Every self-respecting study has to have it.
Kip Hansen (On the move, Stateside USA)
Take Home Message:
"Of course, the findings in this new review are associational, meaning that they prove that people who run tend also to be people who live longer, but not that running directly causes the increases in longevity. Runners typically also lead healthy lives, Dr. Lee says, and their lifestyles may be playing an outsize role in mortality."
The study covers running, tennis, and brisk walking -- but the primary measure was Leisure Time Running -- so may well be a measure of the lifestyles associated with those who have leisure time to go out and run -- privilege, affluence, time to spare from working, family, housework, yardwork, etc etc..
When my wife and I were raising four kids, neither of us would had time for the required 8 hours per week of leisure time running called for in this study. What social/economic class has that much time? None I've ever been in. I think maybe the 10%ers?
James R Dupak (New York, New York)
I read 2 hours per week. Where did this 8 hours per week number materialize from?
Gadflyparexcellence (NJ)
This type of correlation between running and prolonging lifespan is risky and not helpful. Life span is dependent on various factors including diet, stress level, socialization, physical activity and various other factors. Of course, we know what happened to Jim Fixx and more recently to Tom Fleming, two star runners of America. Conversely, there also have been multiple reports of many longest living people in the people whether in Sardinia in Italy or Okinawa in Japan who have not done much or any running at all. Studies have related their longevity to heathy diet and moderate level of exercise, mostly exercise.
proffexpert (Los Angeles)
Those of us who ride bicycles are always surprised and shocked by the grunts and gasps emitted by the runners we pass. If running is so painful, why do it?
James R Dupak (New York, New York)
Oh, those endorphins. And those sounds you hear may be the body adjusting, but what happens to the mind is often another thing entirely.
Fortitudine Vincimus. (Right Here.)
Thank you to the author of these amazing and great articles!!

Highly informative, educational, inspirational, fun and enjoyable!!

This is one of the best features of the NYTimes.

Thank you for many years of inspiration, reaffirmation and advice. Running keep you young and strong -- who needs drugs and alcohol when you can have endorphins! Throw in a personal relationship with Jesus Christ and a healthy diet and you'll be in a super great place in you life!

THANK YOU!!

I don't run, because it ends up bothering my knees too much - even at a slow pace. So I quit even trying and I started doing other forms of cardio, mainly elliptical and swimming, both of which are low impact. I love doing both so I keep the workouts going regularly - and I feel great! I am glad i stopped trying to run because it was just not for me, and you can't tell me that running is the best way to get in shape or live longer. I see runners all the time who are hobbling along. and sometimes all bandaged up - what for? What is the point if you cannot run properly? I have a resting HR of 46 - even at work at my desk. I'll stick with what is working for me - because it is working. Feel great? Check. Lost weight? Check. Good cardio condition? Check. Enjoy working out? Check!
Robin (Bay Area)
I ran for 30 years on and off and always had knee problems. Eight years go I found out about barefoot style running which teaches you to land on the balls (front part) of your foot and not on your heels, which encourages knee problems. Never had a knee issue ever since. I don't run barefoot, but I am mindful about landing on the balls of my feet. So it is not running per se which result in knee issues, it is how you land which does.
Robin LA (Los Angeles,CA.)
My wife has been a serious runner since adolescence and now at 49, she manages 30+ miles of SoCal running a week. While I've always admired her determination, I've come to resent her "runs". Increasingly, her running space feels like an escape. A getaway from laundry, the kids, cooking and probably me. She runs hard and drinks hard and so much of her self-concept is wrapped up in her running. She is a Runner. Equipment? nothing fancy. Jog bra, old shirt and shorts and worn shoes. In local races, within her age group she's unbeatable. Running is overrated, stopping isn't. Thank You.
James R Dupak (New York, New York)
Thanks for the vent, but seriously, why don't you go do some laundry while your wife is out? And do you really resent her wanting to self-actualize in such a moderate way? All I can suggest is that you go fill that washing machine up, have a seat, and read a good book--or even better, go for a run.
Karen (Mclauchlan)
Yeah ...but it can RUIN your Knees, so that by the time you are 60 you have bees-knees that seem willing to want to buckle out from under your legs! Take care of your knees!
Jennifer Hirschfield (palm desert)
I recently started adding cardio into my exercises, and just by doing that I feel so much better. I don't run, but I would like to start. I've heard this before, that running makes you live a healthier and possibly longer life. I think anyone who has got any health conditions should try to incorporate running into their lifestyle. At least an hour a day or 3 times a week would make a difference. If I had more time during the day I might be doing it more. But I will definitely start. After reading this it makes me want to start, and has motivated me to start sooner than later.
Charlie (MacNeill)
Running at least an hour a day! That would be a lot. Go for a routine of 3-4 times a week jogging a 5K. That would be good believe me.
Wayne Griswald (Colorado Springs)
The authors of this article need to look up the difference in causality and correlation. The study is meaningless.

Running didn't help my friend who was run over by a car running at the age of 56.
Evan Ivester (Elkhorn Ne)
This article is not saying running will protect you from anything,its merely saying it will prevent you from dying of natural causes such as old age but for 3 years,if your friend had not been hit by a car he would have most likely died of old age.
Brom Bonz (Florida)
I wonder if it might not be premature to call running "uniquely" qualified as a life-extending exercise. Has swimming been studied anywhere nearly as closely as running?

An octogenarian, I'm heavy on the swimming currently, with 14 different stroke and kick combinations, including a "fish" stroke -- my idiosyncratic add-on variation on the side-stroke -- in which the entire lower body undulates to provide the "kick."

I spent about 25 years with a beachside routine in Southern California that involved 45-75 minutes Hatha Yoga stretches, followed by a 5-mile run at a 9-minute pace, a 30-minute swim in the Pacific and about 15-minutes of rest.

Dancing -- freestyle dancing a la "modern dance" -- or other forms of dancing other than "social dance," which is more like hugging to music, might also be studied. On the other hand I'd concede freestyle dancing might be likened to football, with considerable physical risk.
Rick (Vermont)
As a longtime runner (since 1973) I would say even if its just break even (1hr running=1hr more lifespan) it's worth it. I might even go so far as to say that even if there is a net loss, it's worth it.
S K (Jamestown, NY)
At 70 I have run over 10,000 miles in the last 10 years, 1400 last year, and have competed in 190 races, including seven marathons. Before 60 I rarely exercised and prior to 2002, when I quit, I had smoked for 30 years. I am also employed full time. I have encountered no long term and few short term injuries to my body and my doctor tells me to "keep running". My blood pressure is 90/65 and my heart rate at a 8:30/mile pace is 135 (my maximum HR is 180). Last month I ran 175 miles (including three 20 mile runs) in preparation for a marathon at the end of this month. After marathon training in the first five months of the year I drop down to about 30 miles a week so that I do not overstress my body and just run periodic 5k's. I don't know if this will extend my life (I hope it does) but I would run anyway because it clears my mind, makes me feel great, and I look forward to it each day.
Charlie (MacNeill)
You're 70 and running an 8:30 mile! I'm 70 and have to settle for a 11:00 mile jog. Impressed I am!
Bo Baconator (New York, NY)
Nice job both of you! I'm 56 and I'm running 11+ minute miles. In my 20's, I ran half marathons at 6:05 paces. Now, I'm happy if I can complete a 5k at 8:30/mile.
James R Dupak (New York, New York)
Bo, did you stop running for several years?
Frunobulax (Park Slope)
For over 2 million years, our species (and its now extinct predecessors) engaged in something called "persistence predation". On the hot plains of Africa, we simply walked after our prey for hours and hours until they gave up trying to outrun us. At which point, we merely walked up to them, picked up a rock and hit them over the head killing it.

These animals must have looked at us as if we were zombies.

It was this behavior that allowed us to evolve into the hairless ape we are now. Thus, it seems to me, the best exercise is that which caused (along with millions of years of evolution) us to have the bodies we currently have: long distance walking, preferably in the hot sun.

I walk 5 or 6 times a week, and I cover between 8 and 13 miles each time. I try to walk fast; I cover each mile in less than 16 minutes. I often cover more than 100 miles in a week. I am now 57 and have been doing this for decades now (although I also enjoy running, and do so for a few months before my feet give me enough grief that I have to, once again, temporarily stop for a year or more).

For decades now, I've had a little test I do when I come across someone that looks far younger than they actually are. I ask them if they enjoy walking. The answer is usually an enthusiastic 'yes!'
JayTee (Boston)
I suggest you do a little more research on persistence hunting: it usually involves running.
Carol Mello (California)
It can also lead to the destruction of your knees.
Stace (Ringwood NJ)
It can, but it also cannot... I am a professional licensed massage therapist, and approximately 75% of my clients 55+ with knee problems have never in their lifetimes engaged in running. I've been a runner for seven years now and the knees are great!
Trump Fan (Dallas)
Humbug. High protein meals comprising steaks, a glass of red wine or two and plenty of sex can do miracles to both physical and emotional well being. This nonsense about running is backed by mumbo-jumbo science
Lara (Oakland)
Well done steak, right? With ketchup!
kumar (usa)
I don't know if we proved causality, based on the write up. Is it possible that the people who can (and do) run were going to live longer than those who don't (or cant) ? As an extremely case, if I have a condition that limits my life, it my limit my running capacity too. stated differently, longevity and aerobic fitness are 2 aspects of good health and not a cause and effect in themselves.
emilym465 (Concord NH)
The writer did say that causality was not proven.
Mike (Aspen, CO)
So if an hour of running adds seven hours to my life and I run four hours per day.....
Andre (Brazil)
Of course, these additions “are not infinite,” Dr. Lee says.
Gw (Bay)
Did you read the article, or just the headline?
Perry R. (Calgary)
This article and the original journal article title tend to mislead the reader to believe that running has "special" benefits for longevity. However, this is not supported by the journal paper. The readers here should know that a key excerpt from the journal article indicates that cardiorespiratory fitness (CRF) is the factor that is critical. From the journal paper:
"In fact, after further adjustment for CRF, mortality benefits of running were no longer significant. This implies that CRF mediates the relationship between running and reduced mortality. This potentially causal pathway is supported by previous findings indicating that CRF could be the strongest predictor of mortality."
James R Dupak (New York, New York)
But running is one of the most reliable ways of improving your CRF, and if CRF is one of the strongest predictors of mortality, and running improves CRF, to a degree, than running continues to sound like a very good lifestyle choice.
Jack Vernon (Boston)
Ms. Reynolds is wonderful, but glorification of running is misleading. It's not running per se, but what it does for cardio fitness; any biomechanical motion that elevates heartbeat, and time, are what count. For example, I'm 87, resting heart 69, training 105. After 5 hip surgeries running is out, and my fitness regimen of 30 min. vigorous walking with 12 arm-swinging intervals takes it to 130 3/wk with minimal joint stress. I supplement that with 30 min. of resistance work with bands and 30 min stretching. All averages about 1 hr. a day.
Nancy (St Louis)
You are awesome by the way!
Jason Malnar (Austin, TX)
It's not misleading. Running improves cardio fitness, and better cardio fitness improves lifespan (according to the study), thus, running can effectively improve lifespan. You could most likely also write an article stating that "1 Hour of vigorous walking with 12 arm-swinging intervals May Add 7 hours to your life" ;)
James R Dupak (New York, New York)
I suspect there are other confounding variables at work in your case: diet, genetics, a nonaddictive personality. There is probably an argument to be made that regular running has little impact on some, significant impact on others, and considerable impact on yet another cohort.
Dklauber (Oradell, NJ)
I believe it was Woody Allen who said something like, "Maybe running would add years to my life, but I would have spent those years running".
James R Dupak (New York, New York)
Well, according to the article: 2 hours a week over 40 years makes just 6 months, so Woody is simply wrong.
disenchanted (san francisco)
No mention here of joint pain/disorders associated with running. I suppose that if you have unimpaired knees, hips, back, feet, and ankles, you can run with abandon and enjoy those extra years. I'll stick to cycling and swimming, not push my luck, and hope for just 12%.
Nancy (St Louis)
There's actually no evidence that running is associated with joint pain/disorders... but yes if you have an existing injury then running would likely be out of the question.
Kristin (Omaha, NE)
It sounds like any exercise that boosts cardiorespiratory health is the key, which seems to reinforce another nytimes article saying interval training in general is the most beneficial for the body.
James R Dupak (New York, New York)
Running is unique in that it is a full body exercise, provides significant stress to the bones, and needs to be maintained for a considerable time to result in benefits.
Dianne Wright (Reno, NV)
I am a 68 year old runner. I started running 10 years ago and use a walk/run method and don't care about my time. I show up, run/walk, have a smile at the finish line and no injuries. Running helps your bones and frankly, if you take it easy (we used to call it jogging) it's wonderful. The running community is amazing. All ages, sizes, shapes. Check out Jeff Galloway's books. He started the run/walk method and it works. I've finished about 20 half marathons and one marathon. The distance really doesn't matter and the 5Ks are great fun and usually for charity. Enjoy.
Sunny (India)
I totally agree with you .....
Jeanie Schaden (Rockland, Maine)
This email is really for Gretchen Reynolds - Yesterday, Monday, in the NYT I found an article on a nine minute gym routine involving burpees, planks, etc. I can no longer find this article anywhere! I forgot to save it and it was invaluable because the article also contained video shorts of how to do the exercises correctly. I am 69 and still a gym rat and feel like I'm 40. My husband (who is now 70) and I hike all over the world. We love the Well section of the Times and please, could you tell me how to access yesterday's "circuit" workout!

Thanks,

Running can't be good for everyone... Those with knee issues for example. It would seem that walking is just as beneficial for some.

I would like to know....do decades of running shorten and bow the legs? I would never say it to them, but friends who are runners have that appearance. It has made me wonder if "pounding the pavement" has a long term impact like flamenco dancing. I'll take hiking, thank you very much!
LEH (Bellingham, WA)
But does it help with memory loss? This could mean that a lot of us past 70 could run and run, yet have no idea where we're going or why!

You're welcome?
Back in the Day... (Asheville, NC)
One shouldn't need a study to know that running benefits one's physical, mental and emotional health and quality of life. I've been running my entire life, and have found myself in some of the most serene and inspiring moments and places as a result. Running for me is both exercise, meditation and exploration, taking me away from the stress of the day, connecting me with a deeper self, and surrounding myself with a real, physical environment. Rather than thinking of running as a necessity, view it as a personal pleasure. Run to places that open your eyes, places you'd never go otherwise. The streets of your city, the paths of your parks, the beach, the mountains, or just the suburbs. It's far more than just running, trust me.
Contemplative One (Cincinnati)
Well said!
GBC1 (Canada)
Running requires good health and fitness, good health and fitness does not require running. Healthy and fit people may choose to run but running is a result of their health and fitness, not a cause. As for the effect of running on longevity, who knows, it may shorten the lives of otherwise healthy and fit people.
Ron A (NJ)
It's great that you know more than the doctor and professor who did the study.
James R Dupak (New York, New York)
Who needs science or a study like this when you have the unassailable power of reason. Wait, isn't that what Decartes thought some 400 years ago? Times have changed.
Bonnie (Sherwood, WI)
I'd been a "runner" without much joy...until I was done... so now I'm content to find it added seven hours to my life. I think I will entirely enjoy them
SmallPharm (San Francisco, CA)
I must say that I ran because I love it. In my younger days, I remember wishing that I could run forever. Today, as an older guy, I cannot run much, and when I see someone racing up hills in San Francisco, I am envious and picture myself as a young man scaling hills and trails with almost no effort. Clearly some of us have a predisposition to run.
Ariel Amir (Newport Coast California)
How does the use of an elliptical machine for an hour compare to running as far as it comes to the study?
Trikkerguy (Florida)
Less foot impact and using your energy to go nowhere.
ring0 (Somewhere ..Over the Rainbow)
Greater upper body workout, and gives you the freedom to read or let you mind drift.
James R Dupak (New York, New York)
Elliptical machines give you a great sweat, but their biggest problem is that they are too efficient. Efficiency leads to body adaptations that result in less effort and less demands on the body. The consequence? A bit of a waste of time.
SmallPharm (San Francisco, CA)
I'm surprised the author did not mention the published literature on running-induced neuron stem cell actvation in animals. Being in the regenerative medicine field, I believe running in particular is able to stimulate certain types of repair mechanisms.

Stem Cells. 2009 Aug;27(8):2044-52. doi: 10.1002/stem.120.
Exercise increases neural stem cell number in a growth hormone-dependent manner, augmenting the regenerative response in aged mice.

Perhaps the study is the victim of a bit of conformational bias. Low impact aerobic exercise does not carry the risk of injury and long term joint degradation. Swimming (not in pools with high levels of chlorine) biking (with safety gear) and other forms of extended, intense aerobic exercise are better alternatives. Any long term runner can tell you what a toll running takes on your body and there are too many of us with arthritic knees and hips along with soft tissue injuries that make the extended years we may experience not as pleasant as they could be....
Rick (Vermont)
This is one long term runner that disagrees. Knee problems are not always the case. Been running since 1973 with no issues.

Of course, I don't run marathons. Why turn something that can bring such joy
in to drudgery ?

And swimming can also give joint problems. Particularly the shoulders.
tml (cambridge ma)
Regarding the issue of whether time invested in running returns a sufficiently high amount of months or years gained, one should not see this time as somehow 'lost' time. If running may initially and at times be painful, those who run consistently, and thus the subjects of the study, surely experience the psychological benefits during the runs, whether it be the "runner's high", or a state akin to meditation
Trikkerguy (Florida)
Here is something that hasn't changed in the years I've been doing exercise, aerobic, anaerobic, an increase in strength, and endurance. it's what happens to all of us, no matter our age and physical condition, we all adapt.
Maybe some people forget because of time spent away from exercise, they don't remember how faster they became when they ran every day when they were younger, it still remains the same as we grow older, albeit a little slower, but the improvement happens.
I thought of that today when I came back from a relatively short ride on the Me-Mover. The route I took included rolling grades, it was mostly on sidewalks, some roads. When I returned home I realized the ride didn't seem enough, it was too short, less effort was expended than before, the climbing felt easier, as did the cruising at speed, I concluded that my endurance has increased from previous rides.
The same happens anaerobically, when I put more effort at weight training, those days when I feel stronger, I can feel the results during later workouts, the improvement.
The point being the more investment in exercise, the greater returns no matter the age. We can all adapt, prove it.
Jusme (st louis)
Hey Trikker, you would't have some financial interest in the ME mover would you? If not, we get it, you like it.
Trikkerguy (Florida)
Hey Jusme, no financial interest in the Me-Mover, but a strong interest in trying to get the word out on finding what motivates exercise.
I've tried many self-powered vehicles such as the Trikke, a carving vehicle that I still use, my bicycle, of course, Street Strider, a unique vehicle, but because of a bad shoulder, I cannot use the trikke and Street Strider.
It doesn't matter what turns people on to exercise, as long as it's fun, the Me-Mover IMO fits my needs, motivates me to improve.
You aren't the first cynical response I have heard, but I'm glad I got your attention, I hope other's find what motivates them to find their bodies potential no matter age.
alan haigh (carmel, ny)
To dismiss the fact that one has to be particularly healthy and fit to have running as part of ones regimen strikes me as junk science- they need to figure out how to factor for that and comb out real numbers.

I was a runner until a year ago when a torn meniscus tilted me toward bicycling for my aerobics. I do a 25 minute ride up a very steep hill every other day. Aside from bone density created from the pounding of running I fail to see how my metabolism functions differently with either exercise. I assume I take care of the bones by tending to orchards all day to make my living.
Melissa (<br/>)
I would love to see if these kinds of benefits from moving the body also accrue from other kinds of exercise, in my case swimming.
Sunny boy (India)
Swimming is best exercise among running cycling and swimming. Do it regularly and see results ..
Bob (Dallas)
I will be the shallow one in the conversation....living longer may be big news to some - but running an hour improves my chances about 759% of having a pleasant conversation with someone that is either interesting or a total "hottie". Enjoy life today. That is all.
LarryM (Lockport)
I'm 71 and have been running consistently for 16 years. I live near Buffalo and run all year round, but more in milder months. After several years, I began to understand the effects of my running on me. I cannot prove anything, but I know the effects are good for me, both my body and mind. I still work full time and I know that my running has enabled me to do so. It's not easy to do this. Many days, especially in winter, I'd rather not, but I do. I'm proud of the fact that "I'm a runner." and that pride helps keep me running. I'm well known in my neighborhood as the guy who runs. So many people beep their horns at me and wave as if they know me. I really enjoy that and often I meet people at local grocery store who stop and chat as if they know me, and I guess they do, sorta. And one more thing I know that it keeps my weight down.
Abril Valls Millà (Moià)
Sure that running helps our life in general: you can get a good body, you secrate toxins... I have heared that running is one of the better sports that you can do in terms of getting fit, and, as the article says, increase life expectancy. That's probably because in that type of exercise, we need to use a lot of mucles and we move all the body, not like in other sports.
However, I think that the most important thing for our body , even more important than sport, is the diet. So, as the words say, we are what we eat.
What I mean is, that the article might suggest to the people who smoke that if they exercise three times a week, they will live three years more than the people who don't practise running but eat well and don't smoke, and idea that, in my opinion, isn't realistic at all.
Obviously, the main idea of this type of articles is that we must be moving, a really good advice if you follow it, considering that our body works if we use it. Anyway, we have to remember that it's really important to do sport but eat well is much important.

GB Richardson (Mali)
How unbelievably aggravating to see yet another report of observational research misrepresented as causal, with just a tiny disclaimer at the end, saying "oh, yeah, by the way, it could just be that healthier people run more." No one should be surprised when another study appears in three years showing the opposite. The NY Times is contributing to our current crisis of mistrust in science by over-hyping very tenuous, associational findings in order to sell articles. The real message here is: try to be healthy, you'll probably live longer. Big news.
Ron A (NJ)
The correlation in this study, showing that running increases life, is so strong that the authors were actually able to come up with a formula, 1:7. I think that's very convincing! It seems obvious to me that running increases life because it strengthens the lungs and the cardiovascular system. (No one has to tell me, I can feel it!)
David W. (Bellmore, NY)
I ran for 20 years. I looked like a spastic rhino and felt like king of the road. That was 20 years ago. Knee surgery didn't help. Now I creep and crawl on a treadmill instead of fly on the road. Do my 20 years of running count in the end? (I still have running dreams. Do they count?)
Mickey (Princeton, NJ)
We need a prospective randomized study or twin study over 20 year period involving a large number of subjects with some control over other variables. Sounds ridiculous to obtain, but we should be able to get this study especially in single payor single medical records type of country like Europe or Asia.
Many people with back or knee pain want to know if biking and swimming are worth the time.

Well I know that biking within a few blocks helps both my lower back and my knees so I don't need a scientific study to tell me that is well worth my time and effort. I also love the feeling of the breeze on my skin and the beauty of nature lifts my spirits and sense of well-being. It is also very enjoyable and lifts my spirits to smile it people know that I think they have a really cute dog
Will Goubert (Portland)
Many years of running but mostly soccer injuries have finally taken their toll so I don't run anymore - I do other things like bike & fly fishing besides I don't really need the extra seven hours. I don't miss the running that much just the soccer.
Michael Edward Zeidler (Milwaukee)
I love to read articles about the benefit of being a regular runner. This year is my 61st as a runner since being a high school freshman. I accumulate about 1000 miles on the run paths each year starting in spring and ending when snow stays on the ground.It is psychologically great to be out there running with younger people. And it is fun to take different paths through the city and noticing how neighborhoods change every 1000 feet or so. In spring the running is slow. In late summer the running is fast, and the path is longer. Each year has a fitness cycke. Experiencing that cycle becomes motivation to resume running every March. At age 74 I have completed my first 100 miles in 2017. It's a great feeling to have many years without medical problems, all because of the benefits of being a runner. Thanks for the article Gretchen Reynolds!
dr joe (redlands)
Time of death is multifactorial. I have friends and family who have died already from cancer and other "genetic predisposition" type diseases. Arguably, any form of exercise will give you the same benefit as running, without the work on the knees. In my gym, there are more folks that swear by yoga and aerobics, as opposed to running. I don't remember my parents running an hour a day. They lived until their mid '80's.
Seguismundo (CA)
Running is not for everyone, but living well is. I love running because it makes me feel great. Yes sometimes I get runner's high. I would run everyday if I had the time to do it. Since I don't, I run only about 25-35 miles per week. I must say I don't really enjoy road running, but I love trail running. I live in Santa Barbara California and we have wonderful trails that make running--for me, at least, and for many of my fellow runners--an uplifting experience. So, in a nutshell I would run even if I was told I would lose 7 hours of my life for every hour of running.

Great for you, maybe, but what about other trail users?

Read the book "Younger Next Year", by Chris Crowley and Henry Lodge for some thoughts about the physiology of what may be happening in the body to account for this effect.
Bruce Mohun (Vancouver)
I swim hard for an hour, three times a week. (I come up desperately gasping after my sprint sequences.) Would I really benefit more from running hard three hours a week? (And gasping?) Research has shown, at least back in the eighties, that the best exercise was either swimming or cross-country skiing. (Boxing ranked high, but who needs a broken nose?) Running is without a doubt harder on the knees than swimming. I wonder if swimming was thrown into the mix with this study.
Pat Boice (Idaho Falls, ID)
I'm wondering how this figure of running adding to one's life span is achieved. I know "anecdotes" aren't scientific, but is this study really scientific? I have so many ancestors who lived well up into their 90's and probably never ran an hour in their life - but they were physically active, and most of them didn't smoke. I do believe in science, but I must admit I'm a bit skeptical about these running figures! I'm almost 84 and don't run - only walk. I eat well, enjoy life, drink wine, and I think I'm adding hours to my life!
San Robinson (Seattle)
If the subjects are randomily assigned to conditions: such as running vs no running, and the running group lives longer, that effect is likely due to running because that's the only difference between the groups (individual differences should appear equally in both groups because of random assignment)
tomjude (florida)
Certainly, you are adding life to your hours! Enjoy!
Richard Gordon (Oxford, MS)
The article states that "running, whatever someone’s pace or mileage, dropped a person’s risk of premature death by almost 40 percent" while "Walking, cycling and other activities, even if they required the same exertion as running, typically dropped the risk of premature death by about 12 percent". So, even extremely slow running is better than very fast walking. My question then is "What is the difference?" That is, if running, even extremely slowly, is so much better than even very rapid walking, how can I make sure I am running slowly rather than walking?
Ron A (NJ)
This is a funny thing. There really is a difference because I've experienced it. Twice, that I remember, I had to actually jog to keep up with a very fast walker. Our speed became equal, yes, but you could clearly see our body movements overall were very different. They had a big, long stilted walking stride. I had a short stride, more on the balls of my feet, and my arms moved more rhythmically with my stride. I don't know if that's what you mean.
dr joe (redlands)
The science is not there. I make sure I have my 2 oz or more of wine or other alcohol every day, which also prolongs your life. One hour of running every day probably helps too, until my knees go out. My liver is perfect at 62, as are my knees. I am not convinced.
Tony Mendoza (Tucson Arizona)
Research has shown that running doesn't damage the knees. If your knees go out, it is for some different reason.
CR (New York)
To the all the skeptics preaching their mantra of "correlation does not imply causation", yes, it is right to be skeptical of a claim but that does not mean just because something is correlative it is never causal. We don't necessarily know by what mechanism in which cancer grows in the lungs but smoking has been found to be highly correlative to lung cancer, so would you take the same attitude there? Medical science relies on strong correlative data because there is so much in our biological chemistry we do not know.
Ron A (NJ)
Yes!
Mehul Desai (Milwaukee)
running is good - but jump rope is still king!
1 hour running 700 cals
12 mins jump rope 600 cals
if you jump rope routinely, say 150 turns x 10 sets - alternating front nd back on sets, you could run a half marathon without even a trial run.
Ron A (NJ)
Try it and let me know how your half goes.

Doesn't the old joke ask what good is 7 hours if you spent it running ?

Pacifica (The West)
Studies like this are scientifically bogus. Sure, healthy habits mean better health, but running in no way can halt whatever health woe that may visit us unbidden. I am my own case study: A longtime distance runner, I did two marathons and an 18-mile race over a 13,000-foot mountain pass, all of which required many hours of training over many years. Yet I now have a brain disease that will cut my normal lifespan by more than a decade. I used to read this type of story as gospel, but no more.
josh (Upstate NY)
Anecdote is scientifically bogus. I'm sorry about your situation. But when one looks at hundreds or thousands of people, there are sad stories of rare things in both the runner groups and control groups. On average the runner group still did way better than the control group.
Chris (San Francisco)
So I can waste an hour running, an hour that I will never, never get back, all for the joy of adding 7 more hours at the end of my life? Not to mention the risk that, while running, I will drop dead of sheer boredom. No thanks. I'll wave at the runners as they race past the yoga class I teach.
josh (Upstate NY)
The boredom of staying fairly motionless indoors? That's torture. I'll keep running outside, even as the snow piles up keeping you from getting to your yoga class
Bruce Mohun (Vancouver)
Yoga less wasteful than running? Let me twist my legs between each other and give that some deep thought for an hour.
Cynic (Westchester County, NY)
Gretchen Reynolds knows exactly what "Correlation is not causation" means, and has noted this idea many times in past articles. Yet, she continues to publish this kind of junk science click-bait time and time again.

Junk science? So I take it you've read the original study and analyzed its strengths and weaknesses? Didn't think so...
--JS
Cynic (Westchester County, NY)
Observational study. Game over.
Jacob (OH)
When we look at the lives of many thousands of people and notice that the runners consistently live longer, we wonder if the running makes them live longer. We then take stock of the other things that might explain why runners live longer—maybe they just happen to eat better, make more money, see the doctor, etc.—and measure those, too. Statistically, we (and by we, I mean a curious society) can examine the effects of all of those things separately to see if one thing (e.g., running) is really just a proxy for another (e.g., finances).

While even meta-analyses like these cannot perfectly prove causation, they put the burden of proof on the critic for explaining why running doesn't increase one's lifespan if it isn't one of the many explanations that researchers have tested for and found wanting.
Eddie C Rivera (Brownsville TX)
I started running since 18 years old with my dearest cousin who started me one day! From then on I continue because at the end of my run I feel a high of peace within. Now I am 58 years old and continue to run and feel great doing that action! I don't know if it is good or bad but the present feeling I get is sensational like I said!
Stan Chaz (Brooklyn,New York)
Yes, a bit older perhaps
...but with your knees shot?
And with various other body parts worn to the bone and aching from needless over-use?
And the precious time spent in such hamster-like activities?
Not a good trade-off in my opinion.
Stefan (PA)
Runners have healthier knees than non-runners. The biggest risk factor for osteoarthritis of the knee is obesity
luke (Tampa, FL)
I would think walking would add as many years as running and without the injuries.
Lucas (Virginia)
The impact of walking and running have very little in common when it comes to endorphins, heart rate, intensity, aerobic thresholds, charging up and down hills, lung capacity, core workout, etc.
E.J.Fleming (Chicago, IL)
Just think! Carefully scheduled running can extend one's life exponentially! The quest for immortality has ended at last!
Tony Mendoza (Tucson Arizona)
It said in the article that the benefit plateaus at 3 years. Sorry.
Writelikehell (Europe)
I guess you skipped over the part of the article where it directly states that running won't extend life indefinitely and one can expect to add a maximum of 3 years through running...
SmallPharm (San Francisco, CA)

Could it be that runners live longer because they are healthier to begin with?
Jonathan (Boston, MA)

Charles Edward (NYC)
Similar to what someone else posted, I couldn't wait to read the inane comments people would make. I could predict to a T what people would say: "my grandma lived to a 105, smoked three packs a day and never ran a day in her life."; "All the runners I know have bad knees."

You can run safely on a treadmill like I do. Of course, I do run on concrete whenever I compete in races, but that is only for races. And, who says who you have to either run on concrete or for a race. Running has helped me maintain a healthy body weight and blood pressure. I still have time to work full time and do plenty of other things that running does not inhibit. Let's face it: most of the negative comments are grounded on laziness and the jealousy derived from the lack of will to get off their butts and do something.
Jacob (OH)
Not to mention the fact that it seems like the most obvious sense that running is better for your health than not running. Sure, we can quibble over whether running is truly better than distance cycling or what have you, but it's the most logical thing that of course exercising will extend your life.
Writelikehell (Europe)
The snarky nature of the comments you describe led me to the same conclusion- the people who don't have what it takes to run (the self-motivation required to get off the couch and do something that requires intense energy expenditure) will come out in droves against claims of running's benefits, and with a level of vitriol uncalled for relative to the topic at hand.
E (California)
OK. So maybe my Uncle 102 who eats an egg and bagel and coffee every a. m. For breakfast could extend his life by 3 years. Great. And how will he pay for this? He is still alive and finally slowing down in assisted living. He never had cancer but his heart is finally slowing down. Think mechanical objects. Eventually something stops working. Unless u r Bionic.
Life is in your DNA. Many articles and TED Talks report the science.
FrankM2 (Annandale)
Race walking at a 7 minute per mile pace is reasonable for those who can run that fast, and puts less strain on joints. I don't enjoy that as much as I used to enjoy running, but it works! General wisdom suggests that an aerobic mix is best for many reasons. You can do the mix that appeals to you, with many choices! Some weight training as well, not only for muscle tone, but for weight control. And of course good diet with minimal meat. Not fanatical in any area. Studies come and go, but these general principles will endure.
Bob (Dallas)
I agree with you...but race-walking a seven minute mile is pretty tough. I would guess most readers are running/jogging in the 8-10 minute range.
Stuart (Boston)
Americans, in their quest for immortality, should turn their attention to how that additional cost will be borne in retirement savings, Social Security, and health care provision (particularly joint replacements for the runners).

We need to fully recalibrate our society's need to keep our elderly housed, clothed, and fed (or employed) as we reach past 100 and seek to redraw life expectancy actuarial tables.

In related news, there appears to be no meta-associational benefits accruing to physical exertion avoidant excuse making...
Jim Dickinson (Columbus, Ohio)
If you are not a runner I guess it is hard to understand, but I run for the joy of doing it and the way it makes me feel, not for some magical life extension. It is good to know that there are more benefits beyond just feeling stronger and younger though.

And running properly does not need to lead to joint problems. Knee and hip problems in the US are mostly caused by being overweight, not by being overactive. Runners who witlessly pound the pavement cause most running related joint problems, which can largely be avoided by having good running form.
BCY123 (NY NY)
Maybe. Maybe. These data can never truly rule out just the simple explanation. Folks who run, self select. They would live longer without running because of physiology, attention to healthcare and other factors. The truth is these are correlations not explanations. No matter how complex the analysis this is always the flaw.

This is a self reporting associative study. It is nonsense. Until the authors in a prospective randomized study take 10,000 healthy people and put half on bicycles and half running for the same energy expenditure for ten years and show that there a 20% reduction in cardiovascular risk all the walkers and bicyclist do not need to be concerned about the benefits of their chosen exercise.
Phyliss Dalmatian (Wichita, Kansas)
If I attempted to run, I would have two black eyes. Each and every time.

Thanks. I really want breast reduction surgery, even at 56. But, I'm terrified of general anesthesia. Ironic, considering my professional life. But, maybe I'll try swimming. But, I'm disgusted with the idea of bathing with unknown others. I'm a mess, but a least I can laugh about it.

Bernadette (Santa Fe)
I don't know about the specific quantitative research between running and life longevity, however, I do know that a pool with a broken filtration system becomes stagnant and decrepit. Running has always struck me as the perfect filtration for the body. It mixes and churns and moves the fluids of our internal pipes through all the necessary purification systems. And I for one would much rather swim in the ebb and flow and the power of the ocean; than the motionless lifeless sedentariness of the swamp.

I run because of its immediate benefits, it makes me feel better, my breathing improves, my body is stronger, and it gives me a relaxed feeling. Extended years are just icing on the cake. It's about quality of life, not quantity.

I'm a 70 year old woman who has had a heart condition for the last 30 years and I can't run. I eat a healthy diet, I walk and do yoga daily. I never smoked. So I guess according to this article, I might as well get ready to pack it all in... but looking at the bright side, I won't need a knee replacement.
The Realist (Sydney, Australia)
The article talks about time invested as if it is a negative offsetting the hours of life gained - but what if you actually enjoy running (and there are people like this). In that case you have a double win - doing something you enjoy and extending your expected life.
Mark (Taiwan)
I run 40-50 km per week, and do it for my health, as well as to give credibility to my identity as a Christian missionary in a "foreign land". But my response to the article is simply: We should really give more time to preparing for eternal life, than in trying to extend the temporal life. Really, you've got to live somewhere forever, are you ready? If longevity is for the purpose of blessing others and pleasing your Maker, then we should run with the gusto of Eric Liddell, who inspired me to be both a runner and a missionary. In Chariots of Fire, he said, "When I run, I feel his pleasure."

Running for an hour and I would be dead from asthma.

Bos (Boston)
As someone who used to run marathons, even a short run (10 min) is exhausting these days!

But running should be quantified with other factors. Like intensity, genetics and diet. A lot of ultra-marathoners have sustained a lot of other damages. On the flip side, nothing can really duplicate running. And practice makes perfect. People with knee, weight and other problems can find a better shoes to compensate. Just make sure you give yourself some time every day to do so

A massage therapist once told me running has a medatative component. That made perfect sense to me.

There is a tiny grass park I use for running laps. One place where I lived I ran around my house. Those who say running destroys your body should think of getting off pavement. It's more strenuous too.

Running does not increase the risk of knee or hip problems. A common "folk myth", spreading of which is quite irresponsible to be honest. A number of large studies have settled this, including;

There is no evidence that those who run have more knee problems than those who do not. All the people I know who have had knee replacements had never been runners.

les hart (west chester pa)
May add? Max three years. From what I saw in my medical practice the runners had several orthopedic surgeries and months of rehab. Perhaps it is all a push.
Mason (Queens, NY)
Perhaps, it is that the patients had congenital skeletal issues that led to the injuries. What your patients really needed was some instruction on how to run with their body type, rather than assuming "everyone knows how to run." The fact is most of us need some guidance to run efficiently and a doctor who is more inclined to send a patient with knee/hip issues to physical therapy rather than to the OR. I have been running for 40+ years and at 71 (with a bit of guidance from a Physical Therapist early on) have never had a knee or a hip problem. Trust me, my body like everyone else's has its congenital issues.
Jacob (OH)
Of course, the runners without such problems probably don't see the doctor to take a look at their healthy joints.

michael1945 (boise, id)
The last thing I want to do is discourage fitness, and I hope that everyone pursues the most healthful possible life, physically and mentally (maybe an artificial distinction?). But as a (retired) scientist, I can't resist suggesting that the seven-fold gain of longevity might qualified by some issues:
1) The time investment was probably underestimated, what with changing, showering, buying shoes, dealing with injuries, etc.
2) The time investment occurs in the prime of life, with a job to do, kids to parent, etc.
3) The payoff time may occur at the end of life, with possible a low quality due to cancer, arthritis, digestive issues, etc.
4) The payoff time will be at least half spent with sleeping and other "maintenance" activities, some of them not so enjoyable.
Gregb (Glen cove ny)
You are making an assumption that the time spent in prime years is not enjoyable. I disagree, I run because it's a passion that I enjoy. Even without the potential of extended years, I would still continue this activity

I wish I could run. It's the easiest, most efficient and condensed way to get a cardio workout--maybe not as much fun as cycling or hiking, but all you need are shoes and some place to run. I ran a 10K nearly every weekend in my late twenties and my thirties and now in my sixties, my knees and hips are shot. They know more about shoe technology, pronating, etc. now, but I'm convinced some bodies are just not cut out for running.
Ron A (NJ)
According to my calculations, I'll reach my 3-year plateau after 20,000 miles of running. I'm already half there in just five years. That's fine but what I'm really shooting for is to beat cancer. All the male members of my family (brother, father, grandfather) died of it. Don't know if running will help me prevent disease but it seems possible.
Benee (Montreal)
No running, as will any speeding up of the metabolism, will not deter cancer and in fact it may accelerate it's growth.
John in Georgia (Atlanta)
That's false. Running helps avoid obesity and makes one aerobically fit. These things decrease cancer risk. General high metabolism doesn't promote cancer. Cancer cells divide uncontrollably due to somatic mutations, not because of a high metabolism.

If that is what you couldn't wait for, I would say you need to do more than run!!!
Larry (Idaho)
Too many people overtrain and under recover. This article makes perfect sense. Running does cut back on belly fat and the effort needed does not put joints in danger. In fact, it can improve joints. I am 70 and will run a 5K race next weekend after running for 40 years. I stopped smoking 40 years ago and have enjoyed my running life from a contemplative and physical standpoint. Walking can lead to running.....and better health.

And even if it took a cumulative "3 years of running" for one to live 3 years longer . . . even so! Running is a high point of my daily routine. I would happily go on running, as I have for the past 35 years, even if it did not bring me one extra minute of time on this earth.
Gordon Powell (NY, NY)
My sentiment, exactly, Peter! I would run even if it cost me time from my life, I think. Running is a deep and consistent source of joy and satisfaction in my life.
Benee (Montreal)
You may not realize it but you're addicted to endorphins.
Chris (San Francisco)
What endorphins? I have never, in 66 years, experienced any positive physical feelings after exercise (ex yoga). My primary thought is "well, there goes an hour out of my life I'll never get back. Why did I do that boring, and I don't get a single immediate benefit from it. As for the long term, get an extra day at the end of my life? Who needs it?
giniajim (VA)
Ok, so 3.5 hours of running gets you an extra day. Maybe four hours of time counting changing, showering, etc. Pretty much all of your "free time" in a day in the prime of your life to get an extra day at the end of it. Not sure that's a good trade-off.
Ron A (NJ)
It's a lot of work, to be sure, but, if what the researchers say is true that one can continue to smoke, drink, and be obese and still get the extra years, it may be worth the effort.
michael1945 (boise, id)
And don't forget, a large part of that gained day will be spent unconscious (sleeping), or maybe trying to sleep. Or, worse, doing things you might rather not do (taking meds, having surgeries, seeing doctors, seeking pain relief).
Del (Under the Apple Tree)
Question: Are the joints okay with this?
Glad you mentioned that other kinds of exercise (walking, cycling, and others) help extend our expiration date. I think the key point we all need to focus on is not so much prolonging life but living a healthy life through our golden years right up to our final day. Maybe for some folks, running may prolong their life but they may have serious joint problems as they get older. To me, that's not "quality living."
MandyW (Alexandria, VA)
Is longevity the best goal to strive for? At 76, I do a fair amount of physical exercise (running, walking, yoga, diving, balance exercises) not so much to extend my lifespan as to help preserve/increase the quality of life for however many years I end up living.
Cynic (Westchester County, NY)
Distance Runners Are a Paradox for Insurers Distance running, in particular, has a documented history of injury: a 2007 study published in The British Journal of Sports Medicine found rates of injury to the lower extremities were as high as 79 percent in long-distance runners
Ron A (NJ)
I don't know about insurers. I'd think they'd be happier insuring an exerciser than not. But, you're right about the injuries. Runner's World mag had a story about all the injuries faced by runners. It is very high. However, almost all of those are temporary, such as shin splints and "runner's knee".

THe profound bias in this story is astonishing. These are ALL associations studies not random trials assigning one group to walk, another to run, another to cycle. It is obvious and does not need any study at all that people fit enough to run in the first place would live longer. OF all the varied and prolonged exercise I do, running is the most taxing and hard in the system for me - even more so than hiking, cycling, swimming. Even though this article mentions way at the bottom that all these studies are associational, the headline, lead, quotes and implications support this misleading conclusion that if a regular person takes up running they will live longer. There is NO EVIDENCE here that that is the case. Please stop misleading, guilt-inducing journalism like this.
Jane Mars (Stockton, Calif.)
I've always been "fit enough to run," but if you could run and don't, it is hardly the same thing as actually getting exercise. And many people start running when their only "fitness" to run is that they probably won't drop dead of a heart attack if they exert themselves in the next half hour--they are overweight, lose their breath easily, and are at danger for all sorts of illnesses. They aren't fit...but they go out and get started...a little bit today, a little bit tomorrow, a bit more next month, and a good solid run in several months, and off they go. And suddenly, they ARE fit.
Ron A (NJ)
But why do you say "no evidence" that you'll live longer from running? The entire purpose of the meta-analysis study was to provide that evidence. True, it's not rock-solid cause and effect but it's some pretty convincing circumstantial evidence IMO.
Charles Marshall (UK)
Too little information here to make much sense. So running, no matter how slow, is good for you? OK. But what type of cycling, for example, did they compare it to? Most people cycle at very low intensities, broadly equivalent to a brisk walk. But as an ex-racing cyclist who still trains, I will frequently spend three hours on the bike withan average heart rate over 130, and once a week I'll do hill repeats when my HR maxes out in the 160s. I'm 62 years old with an estimated VO2 max that would be rated as excellent for a man in his 40s. I'll take a lot of convincing that jogging round the park for an hour is going to be more beneficial...
Susan Hibbard (Cleveland)
The article doesn't say that the researchers assigned random people to run and random people not to run. If they looked at what people do for exercise, of course healthier people do more active exercise. This doesn't necessarily mean that the running made them healthy or live longer.
suedoise (paris france)
As Hemingway says in A Moveable Feast: " I wish I had died before I ever loved anyone but her"
Indeed what is the point of running.
Jeff Hill (AUS)
If you look at the book "Born to run" by Christopher McDougall, he makes a valid point, which is we are genetically created for running, our bodies are designed for it, so if some people just sit in chairs all their life, and others do some running, who do you think is going to live longer? This article makes sense to me.

Those other sports are aerobic for sure, but they sure aren't sports that our bodies are designed to do naturally.. running is.

Joann K (Perris, CA)
One full hour of running for only seven hours of extra life.... Not Worth It!
Lois Epstein (Anchorage, Alaska)
I'm pretty certain that the reason for this is that running - even for a half hour - relieves constipation which has to be healthy. While it may be indelicate to admit this, if anyone proves this hypothesis, please give me credit!
dbl06 (Blanchard, OK)
My Mother died on January 28, 2012. If she had lived until her birthday which was February 16th she would have been 106 years old. She never ran a block after she got out of high school. In fact, she never exercised in any way but she was active. Your longevity is in your genes and statistics.
Robin (Bay Area)
So lifestyle doesn't play a part, hmm.
L Maloney (Columbia MD)
As much as I enjoy reading Ms Reynolds' articles, it often seems as if she is intentionally promoting running while avoiding writing about other activities enjoyed by many people, young, middle-age, and old. This article is an example. Last November there were a number of articles published around a study that claimed that racket sports reduce the risk of death at any age. I don't know if that article and this most reacent one are in conflict with one another, but I was surprised by the omission of any coverage of it by Ms Reynolds. Perhaps she was waiting for more studies to confirm or deny the study on racket sports, but she wasted no time in reporting on this latest study on running.

If it is the intention of this column to promote running to the exclusion of other sports and activities, it would certainly be helpful if Ms Reynolds would state it up front.

In the meantime, I'll continue to enjoy Ms Reynolds' article and I hope that she will cover the health benefits of a wider variety of activities, assuming there are some.
HAnnah ARon (NYC)
Excellent points.

If an hour of running can extend your life, imagine what regular, full days of continuing, varied and intense outdoor physical activity can do. (Poor non-runners!) Get outside and play hard. Your life will be longer, fitter and more interesting.
tishtosh (California)
Who said play? We're talking about exercise here. Get out behind the water buffalo and plow the rice paddy, get on a horse and drive cattle all day, get down on your knees and pick fruit and vegetables, pick up a basket and pick grapes, then go home and rustle up dinner while wrastling the kids to the table and helping them with their homework, wash the dishes and scrub the floor, then sit down and spend an hour listening to paps reminiscing how young people today have it easy anymore, while you darn socks and work on the hope chest quilt till it's time to climb in bed and blow out the lantern because 5am is coming round the corner, sure as the sun rises.

I'm a Psychologist. VIGOROUS exercise is an anti-depressant, plain and simple. Depressed clients who walk, tend to continue ruminating. YES, medication is often efficacious, but there is nothing like aerobic exercise that will consistently elevate one's mood.

Some day the Times "science" reporters will figure out that correlation does not necessarily indicate causation. I doubt that it will happen soon.
FYI, a much more likely explanation is that people with the energy to run a lot are generally healthier than those who lack such energy, or that people who run are more concerned with health and otherwise lead healthier lives. But why bother with complexities like that when the public can get all excited about longer subscriptions to the New Yor -- eh, I meant longer, healthier lives?

Ann Spinney (Amherst, NH)
Running is NOT the only aerobic exercise. Either the science is biased, or the New York Times reporters are biased. Or both. I'm sick of seeing promotion of running over other exercise every other day.
Walter (Washington DC)
Indeed! Swimming is much healthier
Chris (Florida)
No, as the scientific evidence makes clear, swimming is not as healthy -- partly because it removes the elements of gravity and force. Swimming is better than no exercise, to be sure, but not all aerobic exercise is equal. Let's get out of our own heads here and believe what science says is true, not what we want to believe.

Or: healthy people live longer and a number of them run, while less healthy people die earlier and do not feel like running.
If so, flogging less healthy people into running will not prolong their lives; in fact, it may well have the opposite effect.

John M (<br/>)
A study with large, but general, results has resulted in a lot of comments that seem to have little to do with this article or the study. It took me a re-read to figure that my own increased longevity fit very much within the 3 years calculated in the study. Nothing was said about people quitting (I did, after 25 years), about injuries (that's why I quit). But there were many scolds who gave testimony to their assumptions. I balance my wine glass on my tight but corpulent abs while I ponder what TV shows to binge during my extra 3 years, minus time out for my grand-kids' graduations. Don't know what to do with the time (meet you at the pool).
Bob C (New Haven, Ct)
So if you run an hour a day, 5 days a week, 50 weeks a year, for 30 years, you've added about 6 years to your life.
Benee (Montreal)
Yes and if you thought you felt you were completely shot at 88 just wait until you're 94 !!!
Adding 6 years to your life merely extends the miseries of old age. Just live naturally and as comfortablly as you can until it's your time to leave. If you like to run then run but if you're doing it to extend your old age then you've got it all wrong.
Const (NY)
I am a runner so this is a pleasant study to read about. To be honest, even if the study showed one hour of running shortened your life by seven hours, I still would be lacing my running shoes up. I run for the mental health benefits running brings me. Any physical benefits are just icing on the cake.
Chris (Florida)
Maybe this -- on top of research showing runners have FEWER joint problems than non-runners -- will finally get the Lazy Boys off the couch.
Benee (Montreal)
Chris, have you considered long walks of short piers?
Chris (Florida)
Not surprising. I've known people who do aerobics, yoga, swimming, lifting, walking, elliptical and treadmill. And they can't run 4 or 5 miles with me, even at a slow pace, on the open road.

Every form of exercise is good. But nothing speaks to your body like simple running, especially on the street. If you have working legs and you can't run 5 miles, you're not in shape. Period.
pm (nj)
Ah, the definitive statement with the angry Sean Spiceresque "period". Perhaps no one wants to run 4 or 5 miles with you.
Dana (Austin, TX)
I highly doubt that. I can swim for miles (literally, at a pretty decent clip), come out of the pool and be totally happy and feel great. With long limbs and very broad shoulders, I'm simply built to swim. I'm currently training for a triathlon and just yesterday I ran 3.5 miles. Today my back hurts so bad it hurts to stand and my knees are yelling at me. I hate running.
Chris (Florida)
You can doubt all you like, but the scientific evidence backs it up. And science -- or objective truth -- is what counts, not what you hate or what you like or what you'd like to believe is so.
DBman (Portland, OR)
First, running should not be looked at as something that is unpleasant, as suggested by the comments that if someone spends a year of their lives running and lives an extra year, what's the point? Runners must enjoy the sport on its own, as it did for me for the last 35 years until an injury (not running related) forced me to stop (temporarily I hope).

It may be that running, or other exercise, by keeping someone lean, active and fit allows them to fulfill their potential lifespan, while being overweight and sedentary, to name two things, are known to reduce lifespan.
Peter Mark (Strasbourg, France)
I am with you, DB. See my later letter...also running for 35 years; I dont run to live longer but to live better. Cheers.I hope you get back to running. And you live in a great city to do so.

Sudden death, after a certain age, seems perhaps to be a blessing -- compared, for example, to death from metastatic cancer in the bones, or a long twilight of memorylessness, dependent on third world disinterested nursing home aides to change one's diapers, burning down the remaining dollars of life savings that might have instead be used for a grandchild's college tuition, for their own economic survival in that savage future ruled by the global billionaires, and, by then trillionares too--a la the Trump-Kirschner dynasty model.

Much of this misses the point in my opinion. To quote Emerson, "It is not the length of life, but the depth.” For me running adds depth and I feel better, but it's not for everyone. If you can, swim, cycle, walk, play tennis,
etc., but find something you like. We are built to move.
Elisa (Westchester NY)
Yes of course. As with nutritional advice, those looking for a "silver bullet" will be disappointed. Exercise of any form just makes sense, but running is one that is accessible to everyone.
GH (Los Angeles)
I am a 64-year-old woman who in earlier years used to run. Now I simply can no longer run. Age has simply taken away the capacity, for reasons I do not understand. I've always been fit and these days I swim long distances and also climb stadium stairs as fast as I can at UCLA three times a week. I still feel great physically and hope that climbing the stadium stairs will be a good substitute for my previous running exercise. We can only do what we can do.
Michael Lum (Dallas)
Good for you! I'm willing to bet your swimming and stair climbing are at least as good for you as running. Keep it up!

So, people who can't run (genetics) or prefer other forms of exercise--we're all "lazy?" Nope, sorry, (sound of buzzer)---wrong.

no its the ones who for 30 years have brought up Jim Fixx as their reason for not running or my choosing to run is stupid and that I will just have a heart attack. Thats my point ..its on the naysayers and their excuses..let me be and let them be..
gw (usa)
John, one of the reasons runners and running are so disliked is association with arrogance. Nothing ruins a great hike like having to constantly worry about some trail runner coming up behind you barking "TO YOUR LEFT!" It may take me longer to get up the hill, but I'll have learned something about botany and bird songs and enjoyed the scenery, and I'd call that a richer life than one of stop watches.

Consuelo (Texas)
To de-bunk the joint damage de-bunkers: I loved running from of 19 to 44: in Texas-98 degrees, 90 % humidity, in New York on freezing days. I ran 3 miles every day for years. I wasn't great at it and never did more than 6 miles. But I was consistent . It was great for weight control as well as cardiovascular health and also mood elevation. I hated to stop. But the orthopedist, who I very much trusted and respected, gave me this advice: " Your joints are going. You have almost no cartilage left in your lower back. On your x-rays your feet look like those of a 70 year old. Your knees are going to give you increasing pain. If you stop running now you will be able to walk wherever you need and want to go for the rest of your life. if you don't stop-and I know how you runners are-you may find that one day you can't walk comfortably enough to lead a full life. So go home and think about this."
I appreciated his bluntness. I stopped running. I started walking and gained 12 pounds as walking took nothing out of me. I watch people lose weight walking and I am amazed because after running for decades an hour of brisk walking up hills was insignificant exertion for me. 20 years later I have switched to swimming and water exercises-100 crunches at the side of the pool etc. It is not calorie burning but does keep muscles tight and is mood elevating. It is equally as time consuming and you have to find a pool and get a lane- actually less convenient. All cannot run until 86 .
idnar (Henderson)
Just because your condition was due to your particular anatomy, doesn't mean it applies to all runners in general.

It is simply not true that runners have more knee or foot problems than non-runners. The most comprehensive research to date shows the opposite.

I have bad genetics in this regard, and have had two minor knee surgeries. Do I still run? You bet! No excuses...

This is good news for us road pounders. My wife runs marathons and I always wonder if it's too much (me, I'm a 5K fiend).

thanks for mentioning the correlation/causation bit at the end. it's important to remember that it's more complicated than run more/live more.
Scrumper (Savannah)
Man has been running for millions of years and our knees are still there. It's only modern life and laziness that has manufactured these doom laden crystal ball predictions that a runner will have joint problems.

If we were still chasing our food nobody would even be mentioning such nonsense.
Zack (Washington DC)
Humans chasing food didn't do it for miles on end. They also didn't live nearly as long.
Naptown (Townie)
No, we would not be "mentioning".....we would not be typing on a keyboard connected to the internet, come to think of it.
William (South Carolina)
I am convinced that it may not be running as the variable. In my experience as a physician, I have noted that my elderly, retired patients that sit around and are not active die early, and those that are active mentally and physically by something as easy as walking, riding a bike, or swimming live longer more fulfilling lives. Running can be hard on the joints in the long haul, and it may not be necessary.
Suzy Beemer (San Francisco)
The article concedes that the association is correlative rather than causal, at the end. But the first paragraph should not state that "No other form of exercise that researchers looked at showed comparable impacts on life span." There is no evidence that running "impacted" the lifespan.
Thorina Rose (San Francisco)
That doesn't seem fair! For people suffering from knee injuries and joint degeneration, running has to be replaced by other activities like swimming or cycling. True, other sports have never induced the lung-searing sense of exertion, that I used to feel when I could still run. Maybe it's time to ramp up the intensity?
Jim Dwyer (Bisbee, AZ)
Health matures around what you do or don't do with your legs. Once sitting and watching TV becomes more important than moving your legs, you are decreasing your time on planet Earth. And if running isn't your thing try doing mini-squats in front of your cooking microwave. Just work those legs.
Lily Quinones (Binghamton, NY)
Too bad the study did not consider the effects of running on the knees and ankles. A person who is in great physical shape can have those issues so imagine someone who is slightly overweight or obese. The additional years of life may be complicated by the physical pain caused by deterioration of the knees and ankles.
Karen Cormac-Jones (Oregon)
Hard on the knees, hard on the heart (remember Jim Fixx?) The original marathoner, Pheidippides dropped dead after running 26 miles. Reason enough to focus instead on weight training and low-impact aerobics. Walking's good, too.
idnar (Henderson)
That's because running's impacts on joints has already been debunked. People with those problems due to running either use bad form or have an anatomical issue.
Joe (Melbourne)
Jim Fixx ate junk food - wasn't the running that killed him
vmdicerbo (Upstate NY)
I have been exercising, mostly running, for almost 40 years. A few years ago my Orthopedist told me that I had some spine compression due to running. He suggested I taper my regimen. I took his advice. I now run about twice a week. Spinning, at least for me, is a great alternative. Also, one of the best exercise machines is the Jacobs ladder. Tremendous workout. If you have never seen one, do a google search. I really miss running on almost a daily basis. But in the end lets all remember we are doing this for our health and any movement is better than a sedentary existence.
Eric L (NH)
I run because I (sometimes) enjoy it. Being consistent with it and staying in shape has numerous benefits- even just improved mood, or better sleep. I'll risk feeling better about myself for decades over a mythical future joint replacement any day. My brother years ago started lifting weights, focusing on core/arm/shoulders especially. Why? He traveled a lot for work and it made getting his bags and suitcases around much easier- less tired when he arrived also. Find an exercise, or a reason, and just do it.

Dave (McKinnds)
100% agree. Fact: People with "running related" injuries get them as a result of horrible form, improper shoes, lack of prep/cool down. Spend just a little bit of time to learn how to do it right and you can and will enjoy thousands of miles pain free.
Scrumper (Savannah)
Totally agree! I hear the same nonsense all the time. Man has been running for approx. 4 million years and we're still here.
Robin (Bay Area)
Well said!!
andrew maltz (new york)
interesting there is no comparison to swimming, famously considered the best exercise because of the cardiovascular workout combined with wider range of muscle exertion an low impact on joints. I suspect running may be the best because however vigorously one swims, buoyancy in the water and inertial movement provide small units of rest between strokes, whereas in running the exertion is pretty much constant, as in those famously popular micro-workouts (or whatever they're called) that deliver the results of a regular hour-long workout in something like 5 minutes, by extreme intensity and no or little rest breaking up the exertion. interestingly, none of this (particularly comparison with swimming- only walking and other running alternative) are mentioned.
OlderThanDirt (Lake Inferior)
First of all running isn't "life." The hour spent running must be subtracted from any life extension created by the exercise. Also subtract prep warm up time, post cool down and catch your breath time, clothes changing time, showering, etc. Also health care time expended for foot or other medical issues traceable to the running. So cut at least two hours off the supposed life extension benefit.

Next consider the heart. The heart is a biological engine built to run every minute of every hour of every day, until it breaks. Think never turning off the engine of your car. Even while parked in the driveway the engine still idles. There is never-ceasing wear. But while the car idles in the drive that wear is relatively light. When the car is taken out to run on the road that rate of wear multiplies several times. Want your car engine to last as long as possible? Run it hard as little as possible.

Consider the brain. During exercise the muscles stake a primary claim to the available oxygen in the blood. Other organs take the hit. During extended exercise those organs suffer some oxygen deficit throughout the exercise period and for a little while afterward. Perhaps a long term regime of exercise causes the oxygen carrying capacity of the lungs and circulatory system to increase enough to cover it. But the brain is uniquely sensitive to oxygen starvation. It has a reserve capacity measurable in seconds. Running bets your brain on your feet. Bad bet.
jjc (Virginia)
For a lot of us running is one of the most enjoyable parts of life, My former girlfriend and I used to run 12 miles every morning, talking effortlessly, which suggests that there was no shortage of oxygen for the brain or anything else. It was just a pleasant time, watching the sun come up, watching birds trying to catch fish, and generally enjoying ourselves.
Ed Reeves (Earth)
This is satire, right? You don't really believe using your heart as little as possible is what is best for it? Why stop at the heart? Lets extend that logic to the other muscles in the body. I am going to spend the next 40 years in a wheelchair so that when I am 70 I will have nice fresh, 30 year old legs. I can't wait to dominate the senior basketball league at the YMCA!
Kathy Celer (Berwyn, Ill.)
"Running is not life. ". What a sour outlook. I run through the woods of my local forest preserve. I am surrounded by the beautiful green of early spring, the lush flora of summer, and the spectacular colors of autumn. I see deer and hear the symphony of birds. It's a great life.
ccoppin (Utah)
I am not a runner but a hiker and walker. I m 76and still walk and hike. My friends who were runners are either dead or have gone through hip or knee replacement. My dead friends may just be statistical anomalies, but they should be a reminder that running does not guarantee a longer life or a pain free one.

Would be interesting to see what hiking does

And by hiking I mean hiking with significant vertical gain

judopp (092356)
How does one maintain running fitness in the process of recovering from injury? It took me three years to achieve a 2 mile run - and then, shortly afterwards, I pulled something in my right knee. While I am healing (pain is going away), I walk. The question is: When I resume running, what should I do differently? Will this take another 2-3 years or should I go even slower this time?
Sandy Beach (Galveston, TX)
Try water running. Some people do it in shallow pools, going forward and running laps, but the best way is in deep water with flotation like an Aqua Jogger (you can buy one on Amazon or ebay). It's a popular way to maintain fitness and work through a running injury while training for a marathon. Just water jog for the same amount of time that your 2 miles would take.
Once you're recovered, you can substitute pool running for some of your road work, reducing the risk of future injuries.
Marc (Montreal)
"Knee" problems (pain) are often the result of muscle imbalances and weaknesses in other parts of the body, such as the foot, tightness in hips or poor biomechanics. Proper shoes can often help, but the key to good correction and injury prevention is to work on strength and flexibility and only return to distance running when it is relatively pain free. Running with poor form is what contributes to cartilage wear and back problems. Have a running coach watch you run (outside or on a treadmill) and check you out. You do not have to give the sport up!
Brian (Oakland, CA)
Read carefully. The headline says 1 hour of running gains 7 hours of life. But buried in the text, it reads the benefit caps at 3 extra years, period. No matter how much you run. You can show a picture of a 100 year old runner, but that's genetics. Unless they would have died at 97.
what me worry (nyc)
Exercises the old ticker... no surprise to me... How many flight of stairs-- walking up is the same as 5 min of running? (Easy to increase heart rate that way.) Swimming is fun but not an optimal exercise.. You float so the bones don't get the necessary pounding to increase/maintain their density) and most people cannot manage a really fast crawl so as to increase heart rate. The lack of gravity eventually results in bone loss.
Trikkerguy (Florida)
If it wasn't for our joints and cartilage we would run until our bodies reached their inevitable end.
Runners injuries increase every year due to the jarring impact, there is no cure for worn joints, our bodies eventually break down which is why cycling has been increasing, no foot pounding. Spinning for hours doesn't seem to be able to take the place of many dedicated runners, so they try alternatives, or they just stop running.
There are stationary machines that mimic running, stepping machines, elliptical machines, etc., but at the finish of expending energy, you end at the same place you started.
Best to cross train with weights, we all should do resistance training based on common sense and many studies along with aerobics, along with exploring running alternatives.
When I'm on the last leg of a Me-Mover ride my legs and core give the impression of an extended run, I get the same high, feel the endorphins, all without the jackhammer sensations of running.
I've tried other alternatives, this is the closest I've found, I've used the Me-Mover for rehab on my hips, I didn't know it at the time, but when the pain disappeared I wasn't sorry.
Running is great, but for most, it's a finite sport, I extended my time with an alternative, maybe others can find something that works for them.

Does this work for elliptical machines? My knees and ankles can no longer take the pounding, so I use a machine. Is this considered running too for this study?
Tim (Boston, MA)
I'm confused by the zero-sum perspective on time spent running v. living longer. When I'm running I'm enjoying my life and not going into a deficit mode; running is not taking time out of my current life but increasing my appreciation of the present moment. I realize that I'm very lucky to be able to run which is part of my gratitude.
Delightful Lawyer (Sedona, AZ)
Even if they smoke, people still get the benefits of running???? This basis for this averments needs to be provided in more detail.
I would be delighted to read the data that supports this absurd claim.

I am a runner, and have done so competitively, and for overall fitness for many years.
I have also spent time reviewing data, research and literature on it. Smokers do not get the long term benefits if running because of the minimum oxygen in their blood created by the smoking. Even second hand smokers suffer similar consequences.

If you smoke and run, your joints hurt, your lungs are strained, and your running form is often compromised. Smokers are not typically long term consistent runners, and do not get the true benefits of running.

There are of course exceptions to this rule, but this article appears to imply that the benefit of running to smokers is not an exception. Data and research needed please!
Ron A (NJ)
I can certainly understand your skepticism. I don't know the answer, either, but I would say, from the way the study is couched that they mean smokers who run will outlive smokers who don't run.
Russell (Boston)
Enjoy your extra 7 hours of life without functioning knees. This guy will stick with swimming and biking as my preferred forms of exercise.
jjc (Virginia)
Been running for 77 years. Knees still okay.
Scrumper (Savannah)
Man has been running for millions of years and our knees still function. I've been running for 59 years and my knees are just fine. It's modern life, inactivity and laziness that creates joint problems. If we still had to chase our food nobody would be complaining about knees or any other joint.
Kim (Carpentersville IL)
That's great that you enjoy swimming and biking. I like both of those sports as well. However, for me, there's nothing that provides the feeling that running provides. Bottom line, everyone has their thing - it's all good. You don't have to tear others down who like to do different things than you. By the way, my knees, ankles and all other parts are feeling great, thank you.
Jack N (Columbus, OH)
What do we know about swimming? As a runner, swimmer, and biker, I suspect that swimming has the best long-term effects.
what me worry (nyc)
No. Swimming result in bone loss as gravity is not involved. Also most people can't do a prolonged rapid crawl.
Bjk (Istanbul)
I thought I was reading something intuitively I knew all along. After having been running nearly 33 years I know how I feel when I run and when for a long time I don`t. My body always telling me what is right and what is not.
Thanks for the article to Gretchen and to the researchers. I am sharing it with my kids and friends.
Maura Sullivan (<br/>)
As a long-time runner approaching 50, I would not run the same calculation by subtracting the six months spent running from the 3.2 years increase in longevity. This implies that that time is wasted - not spent living. But the time I spend running is incredibly valuable to me - it's an addition, not a subtraction. When I'm running I feel alive, strong, and focused. There are moments of being completely in sync with by body and the environment. I notice the weather, the trees, sounds. To me, it's an extra 2.8 years of life to live, plus a gift of six months spent running.
Douglas Cunningham (Kalian Turkey)
I agree with you completely. The time spent running is very enjoyable and I was surprised to see the author equate it with time spent dead.
iPlod (USA)
The stark truth is that people who run regularly are generally already better educated, not overweight or obese, wealthier, less likely to experience domestic violence or divorce and less likely to smoke, drink excessively or use drugs improperly. In my home state of Massachusetts, comprised of 361 cities and towns, one can observe the differences on a short drive between communities of different socio-economic status. The end result is that higher income people are living longer with less chronic disease than lower income people.
Robert Barker (New York City)
Running back in the day was part of our survival as an animal. We ran our prey down. Running was a necessity not something one did to "stay in shape."

Running is a primal instinct, as such our body's probably do well when being use as designed.
Karen Cormac-Jones (Oregon)
"Running our prey down" implies that you see it and run towards it. Unless it's a cheetah or a gazelle, you would not be running 10 miles to catch it - more like 1 or 2 miles. Also - hunter/gatherer has always implied that the people with the babies and the mammary glands were the gatherers while the people without the babies and the mammary glands were the hunters. The young men would be the likely candidates for the short-term runs to catch prey. So I'm not buying the whole "everyone can run endlessly on winged feet and no one gets injured" bit.
Ron A (NJ)
I think we survived as a species by outsmarting our prey, not running it down.
Jon Harrison (Poultney, VT)
Like the author I run and cycle and walk my dog daily. I also walk whenever I can for errands, etc., rather than driving. I run a bit less and cycle a bit more now that I'm older, but I still run 3-4 hours per week (except in winter, when it's usually too cold for me). I've been doing it for 41 years now, so hopefully I've banked some extra years of life.
professor (nc)
I am a runner and I love it! As long as I buy appropriate shoes and stretch before and after my run, I have zero pain. I wish I had started running when I was in my 20s.
Keating (California)
You can't have it both ways. Either "...an hour of running statistically lengthens life expectancy by seven hours" or "the findings of this new review are associational meaning that they prove that people who run tend to live longer but not that running directly causes the increases in longevity." If I were not already a runner, this study would do nothing to persuade me to start.
Mary Kay Klassen (Mountain Lake, Minnesota)
That might be applicable to younger people. When it comes to what we know about DNA, it is a different story. My grandmother who was from German and Ukrainian background, walked everywhere, never drove a car, was thin, didn't drink or smoke, and she lived to 3 days short of her 95th. birthday. My mother on the other hand had both scarlet fever and rheumatic fever, was always sickly in school, quit college after two years, married had two children, and had several miscarriages, she was active but not in any physical way because of her childhood. She had second hand smoke from my dad, never drank or was heavy until about 10 years ago. She is 96 but her mother who had a Swiss background had 5 cousins who all lived to be 100, whose names were Welty related to the writer Eudora Welty's father, as he had a Swiss background, too. Both DNA, and activity are important especially is an unhealthier lifestyle that many are currently living, today.
paul (st. louis)
Correlation or causation? I suspect only correlation. People who run are less likely to have severe physical problems.

B (Tornado alley)
"running 45 minutes, 2 miles daily"

Must be a typo. I can walk more than 2 miles in 45 minutes.

Am I misunderstanding you, or are you "running" two 22.5 minute miles a day? That's not even fast walking.

Alan Day (Vermont)
Running is so hard on the knees -- walking is a much better exercise. Same for ice skating, hiking, and biking.
Robin (Bay Area)
Simple fix- you are are landing on your heels- that's causing the knee problems. Land on your forefoot. http://runforefoot.com/forefoot-striking/
what me worry (nyc)
Walking unless it's race walking or as fast as possible walking that will increase your heart rate is a neutral (your body expects to move gdi!)"exercise." I walk as fast as possible and up hill to get some cardio benefit-- but stairs do it..as in interval exercise. (Three flights to get the hear a pumping.) Your heart is a muscle,too. Fast walking (30 min a day) will help regulate blood sugar levels.. possibly do something for cholesterol but is not a way to lose weight.. That is the closed mouth exercise.
Ron A (NJ)
Lots of people find hikes in the mtns very tough on their knees. And, some bike rallies, like the upcoming French Creek Tour, are very hilly and murder on the knees. Ice skating, hockey-style, with its many quick turns and stops, can rip your knees apart. Unless, I misunderstood and you're against these things.

Walking's fine, just takes so long to get anywhere, lol. Really long walks invariably result in blisters for me. I'll be addressing that issue in two weeks, though, as I signed on to a 22-mile walk. (I'm going to try taping my feet ahead of time.)
Howard (Los Angeles)
How about 8 hour, 5,000 , hikes? One can get into great condition with this kind of exercise. Also a patient attitude to life can help.

Clytie Rimberg (Lake Oswego OR)
Try rowing! It is excellent aerobic and strength training, gets you outdoors and is easy on the joints esp the knees.
Ron A (NJ)
Sorry to hear that but won't you eventually heal and be able to jog slowly? Maybe, it would work on a softer surface like sand at the beach or a gravel trail?
Oso Rojo (California)
Wow, a whole extra three years. I am a healthy 75 year-old woman. I walk and revel in the glorious hills near my home. I do aerobics to music in a room full of happy upbeat seniors. When the weather permits, I swim in an outdoor pool. Running is not an option. These kinds of articles make me crazy.
Rockfannyc (NYC)
Jeez, people. Relax. If you love running, then run! If you don't, then don't.
Lisa (Detroit)
Take it from me, get off your couch. 51 yr old, never had any health issues until recently with severe pain in the left back and a whole lot of dizziness. The doctors had no clue (I have very little faith in the current medical establishment-they are basically clueless, no idea what they teach them in school but we are churning a bunch of money grabbing, greedy "doctors" who have no interest in their patient). I took matters in my own hand and after checking off the usual suspects, upped up my exercising. That did the trick-the pharma industry will want you to get totally dependent on meds, but resist and get out there. I love this article. Very timely.
Don't (Run)
Running is horrible for your body; that is, it's high impact. Hike/walk, but never run. (Ask anyone with a Med degree/background this: it's one of those secrets they hate to tell since they want people to be active and running has achieved sacred status in society for some reason so they hate to be honest about how bad it is for you even though they know most people will not stick with it due to its demanding exertion and multiple area body pain and degradation). Best is low-impact exercise: swimming, cycling, rowing, etc. If you have to run, at least do it on padded tracks or soft ground, never pavement/hard surfaces. Your knees, hips, feet, lower back, ankles, etc. will be shot by your 50's at the latest no matter how HW proportionate you are (i.e. you aren't putting more stress on your joints from excess weight) if you run regularly, especially on hard surfaces. Humans are not even yet evolved to stand upright; we are far from adapted to hard surface (or even any surface) regular distance running. Extra years, or being HW proportionate, are not worth being in pain for decades, especially when there is so much low-impact exercise (some of which also helps tone/strengthen your upper body as well instead of just your legs: with no damage accrued either). Running fails the cost/benefit ratio. Exercise intelligently: don't beat and grind your body down with high impact exercise.
what me worry (nyc)
Impact is what builds bones. Before age 40 -- and PS hopping and jumping might help build bones. Osteoporosis is a problem fo slender
Caucasian women...
Swimming is rarely exercise.. One could play badminton or tennis, ballet, jazz, or ballroom dancing.

One can do interval running/jogging when one is old. A minute per interval.
Robin (Bay Area)
Wrong- the impact is great for your bones as it strengthens them. It strengthens the heart which in turn creates greater blood flow throughout the body, which feeds the body of needed nutrients. It is the best exercise out there, bar none. Sorry you feel that way. The hip/knees/lower back issues arise from people landing on their heels instead of their forefeet. This is from using overly cushioned running shoes. See: http://runforefoot.com/forefoot-striking/
Trikkerguy (Florida)
There are alternatives, cycling, trikking (carving like skiing), Me-Mover (like climbing stairs) easy on the joints. At 79 years old those alternatives work, just depends on what fits your comfort zone.
drmichaelpt (acton, ma)
Many confouding variables, most salient: are not runners more health aware than no. runners?
June (NOLA)
So many people commenting about their former running days cut short by injuries. Everyone who loves running should look up Jeff Galloway's run/walk/run method. He was an olympian, is 71 and has run over 70 marathons. His whole message is to remain injury free, run until you're 100 and enjoy life.
jjc (Virginia)
I should stop when I reach 100?
Trikkerguy (Florida)
When I'm on the bicycle trail with the Me-Mover I get a lot of questions and interest, the cyclists see this as very different, not in the mainstream of acceptance.
I read about runners injuries, I've talked to runners that can't run anymore, bottom line it seems to be for many that different isn't readily accepted, the crowd is not doing it, so it can't be good.
Yet the Me-Mover along with other running alternatives are avoided, or not researched. Defeat is accepted, the injuries will not allow the same life style, depression takes over.
Being in my late 70's I have to be cautious during exercise, I've experimented with different self-powered vehicles, what gives me the best results.
For the last year, I've been increasing my riding distance, climbing steeper grades, my endurance has grown which proves even the elderly can take advantage of aerobic training. I also weight train and do leg routines which I believe helps me propelling the Me-Mover.
Find something that will motivate, that's what works for me, something that compels you to use your body more than you would believe you could do, you can if you take the first steps.

Just curious. Why just running? What about, say, an hour (or more) of cycling? Keeps me fit and keeps me sane.
David Henry (Concord)
Exercise in all its forms improves your daily life. You feel better.

Just find something you like, and DO it.
Concerned MD (Pennsylvania)
I have found that high intensity intervals are the most effective and efficient workout routine and have been doing them for more than twenty years. They keep me fit and thin and provide a sense of mental and physical well-being that is hard to describe, but leaves me to believe that endocanabinoids are involved. (Hey, I came of age in the 60's and did inhale). The intervals are brief....45-60 seconds or running hard, climbing stairs, spinning with tension on a bike or sprinting freestyle stroke in a pool.....followed by 2-3 mins of rest or the same activity at leisurely pace and repeated for about 20-30 mins total each day. As you get more fit, it's actually enjoyable, especially when you are done and in that zone when it feels like nothing else that day can hurt you. It's the only true fountain of youth out there folks!
Jane Hughes (Pax, WV)
The word 'may' says it all.
Dr Elsewhere (New Orleans)
If you don't live those extra years, you'll never know it. "Now" is all any person can ever experience.
The focus should be on the negative side effects of running, as mentioned by numerous comments from your readers.
Further, from reading the NYT obits daily, it appears that the featured departed did not share an obsession with running.
Maria (Spain)
Part of the problem with articles like this are the comments. Jeez people.
paul (blyn)
This study and a million others are creeping at a glacial pace at what nature already knows, the equality theory of life ie everybody gets an equal amount of good and bad in life.

Some day some genius like Einstein may find out the formula like in physics for every action there is a reaction.

There are a infinite number, definitions, types, places of happiness and unhappiness than only nature knows.

It could very well be true that running increases your life span a bit, however to many people it is a pain in the ass to do to get a few more yrs.
Sue (Vancouver BC)
I've never been able to run as a form of exercise, due to foot problems. Let's see a column about what brisk walking does for lifespan...
James M (Philadelphia)
Without delving into the specifics of correlation not equaling causation- what an incredibly irresponsible headline. This is one study and is being treated as fact by the normally cautious NYT.

This, as much as photoshopped images of models on the cover of magazines, impacts Americans' troubling relationship with diet and exercise. There is no silver bullet. Health takes diet and exercise, all in moderation. Promising that you'll live seven years longer if you run five minutes a day is absurd.
Johnny Scher (Ann Arbor)
correlation≠causation
Linear regression tests associations between two variables, in this case, time spent running and age at death, not causality. There may be other confounding variables (people who exercise more are more likely to eat healthier) that affect the results. This article needs to be more tentative in its title.
jordan (lexington)
Did you not read the article? They controlled for external variables.
Emily Clough (Newcastle upon Tyne)
Linear regression allows you to test association WHILE CONTROLLING FOR OTHER VARIABLES. It is clear that they have controlled for a number of possible confounding factors.

A slight correction: correlation does not NECESSARILY mean causation. Sometimes it does.
Mark Shyres (Laguna Beach, CA)
Jim Fixx died at 52.
James Beard died at 82.

Fixx, if you know anything about him, had a genetic disease, and running did indeed extend his life. Research before you write.
Wooh (Hooh)
Jim Fix was a formerly obese man and saturated fat vacuum, whose male family antecedents died of heart attacks in their forties.
Running may have added that extra ten years to his life.

When they autopsied the dude, mars bars fell out. (Three clogged arteries due to diet, actually)

Jack LaLane is a better example.
kris (san francisco bay area)
To be fair, Jim Fixx had leukemia as a young man and fought that for many recurring years. Drugs and chemo did him no favors. It is thought he died young because of all that treatment wreckage.

Just sayin'...

In general I have no use for this kind of article. I do what I can (which is more than most people). But I care more about the quality of my life, rather than longevity.
VinceM (Niagara Falls)
If you want to live longer, read Luigi Cornaro's Treatise on the Sober Life. It is calorie restriction that extends life, perhaps running helps manage the over consumption of food in our modern diets. Cornaro wrote this in the 15th century. He exercised minimally. He lived to be 98 on a total of 12 oz of food per day. He wasn't a vegetarian but he did consume 14oz of wine per day.

With the word 'may' the story holds no water. And they paid the writer for this trash?
Jay Cordan (<a href="mailto:[email protected]">[email protected]</a>)
Do you understand how science works? They catch their phrasings because while it's associated with a higher chance of a longer life span, they can't say for 100% of people no matter what add running and you will live longer. Ergo, even if it's 99%, it's a ''might" not a guarantee. That 'may' you dislike actually shows scientists that it's better reporting than the stuff found in tabloids "eating XyZ veggie will cure cancer!"
Katonah (NY)
Ah, but all around us is "may."

You seek a level of certainty that may be unattainable.
JMM (Worcester, MA)
Do you mean to point out that "may" connotes permission, while "might" connotes conditionality?

You may run an hour. That hour run might add 7 hours to your life.
Miss Ley (New York)
Uh-oh, the last time I ran was with my late husband in 1979, twice and after much cajoling on his part. Yup, he used to call me 'Coach' as a joke. After reading this article by Ms. Reynolds, the latest on Phys Ed, it's 'SNEAKERS FOR EASTER' for everyone I like, and chocolate bunnies too.

I'm good with a 12 percent reduced risk of early death. Personally I think longevity is over rated. Without quality of life, time is no automatic gift.
florayn (New York)
So sorry for you! Running has been a joy in my life since I can walk. For me running IS quality of life, without running no quality of life. The seasons changing along my route, the complicity of a well known route, the wind in my hair, my heart rate slowing going up, my brain knowing it goes for a spin, I can only resume it in one word: freedom. With age, I look a my body slowing down, my muscles aching more, my joints more rusty, the time longer between runs for my body to bounce back and still I think: how lucky I am to be able to run! Not one run when I don't congratulate myself like I would an old friend for a job well done. LeoK, you are missing on something. Get your sneakers on and get some fresh air!
Chris (Chicago)
I'm just over a year into sobriety. I run 6 days a week at my local track. My routine is 6 400m laps. I average about 76 seconds a lap, with about 90 seconds rest in between. This simple routine has radically transformed my life. I have lost almost 30 pounds and haven't had a single bout of depression since I started. I feel great as soon as I finish the workout. My work and personal relationships have improved dramatically. There is something magical about running. The whole routine takes about 30 mins from start to finish. All the self-help books in the world couldn't result in this level of freedom and happiness. I'm a 28 year old type-1 diabetic and I have found the secret to happiness: Stop eating sugar and run 6 400m laps every day. It's free!

walter schwager (toronto)
As some commentators have carped, the link between running and an increased life span may be correlational. However, more rigid experimental studies have found that running (rather than lifting weights) decreases the flexibility of one's arteries and, most importantly, an increase in exercise combined with diet and weight loss reduces the severity and incidence of type 2 diabetes. That is enough evidence to get me out of my chair and to the gym (I suppose running can be done on a treadmill?). Moderate running also improved the strength of my leg muscles, so it's easier for me to get a book or a bottle of scotch off the top shelf.
Meredith (NYC)
Walter....good thinking. Controlled studies by top researchers show that climbing up ladders to get a book or a bottle of scotch off the top shelf leads to dramaticaly increased risk of falls, thus bone fractures!
iPlod (USA)
Walter: Did you mean to say that running increases arterial flexibility?
Meredith (NYC)
Good point and motivation to run. Or maybe move the book and scotch to a slightly lower shelf---still get a stretch, bu you avoid falls from losing balance reaching for the top shelf. Then could be laid up and can't run. Who knows what can happen?

I've known 3 avid runners in my lifetime. All 3 died from heart attacks in their 40s. Arbitrary numbers though.. gotta love em. Breathing can add years to your life.

Shoveling and heaving manure into a spreader pretty good workout. If you wear a suit all week and clean out the hog house on Saturday--yup sure, you might die young!
Nuranthe (New Orleans)
I wonder when they compared running and walking, if they were comparing the speeds at which people moved. Some "runners" are just kind of plodding along, while some walkers cover a lot of ground very quickly. I would think getting the heart rate up means more than exactly how you're moving your feet....

Perhaps people ABLE to run are simply in better condition genetically and that's why they run. So, someone unable to run because of a genetic or other health related reason dies earlier not. Ecuador they don't run but because of said condition.
Wordsmith (Buenos Aires)
JAY, one of the greatest marathoners of all time is Ecuadorian Rolando Vera, who won the San Silvestre half marathon in Sao Paolo, Brazil, FOUR times. He won most United States marathons and those of many other countries, as well as Olympic medals, etc. He (still is) 5 feet 4 inches tall, and has been described as having "the engine of a Mercedes in the body of a Volkswagon."

In his quarter marathon in Quito, Ecuador, in which I ran, his performance against some of the greats in the world was disheartening, even to the ablest.

Does that prove anything? No. Nor does your comment.
Nancy (Great Neck)

TJ (Nyc)
AAAAAAHHHH.

Running may increase YOUR life span (though that is questionable from this study) but reading studies poorly reported in the NY Times will probably prematurely end MINE, either because I'll have an aneurism or shoot myself.

People. Repeat after me: Correlation is not causation.

The scientists recognize this (one is even quoted as saying so). The Times does not.

There are two possibilities here: either running is "uniquely" lifesaving (compared with swimming, cycling, walking, etc) for reasons we can't imagine... or running is actually HARDER than those other activities, and only the fittest people do it.

I run. I swim. I walk. I kayak (a lot). I bike (not much).

I can tell you that of all of them, running is the hardest. If you have foot problems due to diabetes, (or neuropathy from cancer treatments), or heart problems, or other health issues.... you probably will swim, walk, kayak, bike, or use the machines at the gym rather than run.

And you will ALSO have a statistically shorter lifespan.

It's not that running is uniquely valuable. It's that running is a great filter for health--if you're in the top percentile, health wise, you'll enjoy it, if you're not, you'll find something else to do.

SIGH.

Times, when are you going to require numeracy of your reporters?
Markle (Murphys, CA)
I can always tell the new people in town. I live on a nice country road and the runners and bikers have a great time for approx. two weeks, running and biking and then they get really tired of all those hills and dales and I don't see them anymore.
Then a new person buys a home and buys a jogging suit or a new bike with a new bike hat and a sparkly light and they set out to get all healthy.
One 45 year old guy had one room all set up like a gym...he died on the stationary bike. His athletic wife found him slumped over the bars. Healthy looking guy too.
don (honolulu)
From the article: "Of course, the findings in this new review are associational, meaning that they prove that people who run tend also to be people who live longer, but not that running directly causes the increases in longevity."

So the writer did say exactly what you suggest be said. However, I do think it should have be more prominently and emphatically stated. And the headline should have read "...Association..." rather than "May Add 7 Hours." which just as accurately could have stated "May Not Add 7 Hours....". By choosing "May Add.." they are implicitly favoring causation.
Mike P (Champaign-Urbana)
This is the exact thing I just ranted about to my neighbor at work after reading this 'article.'
Kurt Mehta (New Jersey)
Its important to be cognizant that correct running technique is critical to being able to run over the long run. Runners are often prone to chronic injuries when they run by putting stress and weight on their heels. Again, 3 additional years is pretty good if you can still smoke and drink

My occupation required that I use my right arm for the hard part of sawing, hammering, and etc. in the building industry. My right shoulder is worn out because we were not made to do the same thing every day for years on end.

My brother-in-law didn't run for 30-35 years and his hip/back gave out anyway. Of course he 50 was pounds overweight the entire time so that may have had something to do with it.

On the other hand, I've run consistently over the last 44 years and all joints are still going strong.

Note that different people react to various stimuli differently...your mileage may vary!

Or could it be that guys and gals that run an hour a day live longer simply because everyone else that tried it died in the attempt...Survival of the fittest.

The famous jazz and ragtime pianist, Eubie Blake, lived to be 96 and smoked a pack a day from the time he was 7 years old...And he tickled the ivories almost till the day he died...Same with George Burns...A cigar addict till his 90's.

I'm guessing if you love life, like people, laugh often, have joy in your heart and eat fairly well...You'll do fine...Better than most.

Paxinmano (Rhinebeck, NY)
And the great Satchel Paige was quoted as saying, "every time I get the urge to run, I lie down until it goes away." When asked how he stayed in shape he said, "I just jangle." Pitched in the major leagues well into his 60s, though no one knows for sure how old he was. When asked his age he said, "how old would you be if you didn't know how old you was?" If one gets this level of insight and humor by not running, I'd say focus on perfecting the art of "jangling."

The perfect exercise, the holy-grail of fitness, the ultimate, the best,... The reality is that human bodies need movement. To be sure, running is natural to our species but it isn't the only effective movement.

My knees hate running but love bicycling, a couple I know got really fit ballroom dancing, others like to hit the gym, walk, jog, fence, row,... a whole lot of different forms of body activity. My guess is that all of them produce the same general positive effect on health. No single one is perfect for everyone.

Actually the best exercise is the one that you do willingly and miss when you don't do it.

Um, has nobody noticed the massive typo in the headline? An hour of running will add 7 HOURS to your life, really, hours?

annberkeley2008 (Toronto)
I ran 6 days out of 7 for 30 years - mileage about 60-70K weekly and have to say I did it because it made me feel good. You get up a good sweat, feel very clean, both inside and out, and also feel a surge of energy. It's all probably just endorphins. I once got locked in a cemetery, which was part of my run, and tore a long strip in my thigh climbing over a chain link fence. I felt no pain and the doctor stitching me up was shocked that I didn't feel her doing it. I think running simply makes some of us happy - it's perverse but there it is. I have bad knees but can still walk my golden retriever.. For some of us just moving through the air is a delight.
Phil (Nashville)
Thanks, Ann. I'm still at it 25 years after starting to run seriously. I agree with everything you said.
Yoido (Seoul)
I think a lot of runners will agree with what you say. I too feel clean, healthy, normal, natural, strong, fair, human... and, most definitely, happy after a good run. So I would continue to run even if running cut my lifespan short by three years.

Stressed out or emotionally or physically not well? Try running. I once heard a man who beat a life-threatening cancer with running say, "All of us carry with us the very best doctors and medicines we could ever possibly have: It is our legs!"
what me worry (nyc)
If your knees get really bad (I need a wheelchair pain) -- knee replacement is marvelous. I can now jump, hop, can't skip, and have a halting run... but can walk very fast and go up and down stairs. You choose how long you might actually live and subtract 20 -- surgery is good for about 20-- prob more if you are less active years).. Replacing the replacement on an old person is an iffy procedure. I lived with pain for about 12 years before i had it done at 70. I still love my cane (self-defense, ladies!), rarely leave home w/o it. Don't usually put weight on it.
Anne Zimmerman (SF)
Maybe it's not just running itself , but the ability to run which is part of threason runners live longer. Running means you haven't had an illness or injury that prevents you from running. Avoiding those types of injuries and illnesses is the key to having a quality old age.

I just filled out one of these "how long will you live" calculators on line for a fictitious average person: a 50 y/o college educated man of average size, who lives a prudent life, has an unremarkable family medical history, etc. But he never exercises. He is expected to live to the age of 87! Exercise adds three more years to his life. If you hate to run, if it is a chore like flossing your teeth, why bother? The trouble with this calculation is that nobody is really average. Exercise may have a huge benefit for a subgroup of people. Also, the study talks only about death, not the age at which the first symptoms of cardiovascular disease arise. Modern medicine can keep you alive but unhappy for a long time. Who wants that?
Dan (Arizona)

Jim Fixx who helped start the running craze in the '70s, died in his fifties. He had an inherited heart defect that, if I remember correctly, was undiagnosed. He was greatly overweight before running, and probably extended his life by five to ten years. I believe his father had died of the same thing, but even younger.

Lots of negative people commenting either: a) they cant run; or b) envy runners.
Norton (Whoville)
Sorry to burst your bubble, MM, but running is not for everyone (certainly not for me). I don't envy those running fools one bit. I get my exercise walking, but have to avoid a lot of them as they nearly run into me all the time and I've almost been knocked down a few times by these morons who don't pay attention, so intent they are on their "perfect" running exercise (or else they have headphones taking all their attention away).
So, a) not being able to run is not a moral failing and b) I hate running/runners/anything to do with that useless activity, so why envy those people?.
Martha Goff (Sacramento CA)
This is all well and good...until you take a hard fall and break your hip. At my age, that could take me out of commission for months, if not forever. I'll stick to walking, thanks.
Andyinla (L.A.)
So Jim Fixx and Copper Canyon runner "Caballo Blanco" Micah True should both have lived forever, or at least not had the heart attack that killed them.

Wrong. Exercise trains your MUSCLE, it DOES NOT prevent heart disease or heart attack and does NOTHING for cardiovascular health.

"The Textbook of Medical Physiology states that exercise makes the stroke of the heart larger and more powerful, making more blood flow per beat. However, the heart then beats at a slower pace, so the overall difference in oxygen transfer is virtually nonexistent.
Artery size increases, too. You would think that this would prevent the arteries from clogging. While it
does slow the rate of clogging, because it takes more time to fill a bigger diameter, it doesn’t stop the heart attack – it just delays it somewhat.
More mitochondria are produced in the cells, too, but this doesn’t increase oxygen transfer, either. These reasons explain precisely why marathon runners die
of heart attacks. Arterial clogging still occurs during training."

What the "bleep" is premature death? Is there a date stamp on me someplace with my normal death date? On my lower back where I cant see it?

General advice. MOVE! Move much more then you already do and make a decent amount of that movement brisk! Reality, that block or two you have been walking to work, is NOT you exercising, its you doing what you're adapted to doing! NY'ers; Ever notice how out of shape so many construction workers are? Why? They are adapted to what they do, so they grow fat with all the extra food they think they burn at work.

While its not the root of the word - I always tell my clients to look at the term EXercise as meaning EXtra movements. Not what you're adapted to doing. When you do more then you normally would, or are adapted to doing, and its an exertion, its exercise. Its EXtra!

EXercise is always extra, extra work - or its not exercise.
Frequent Flier (USA)
You're probably right, but that sounds awful.

it's not just that running (or other exercise) gives us some time at the end. It's that people who exercise are healthier for longer--and therefore better able to enjoy other activities as well.
Jk (Portland)
I want to state the obvious, which is that people who can run are probably healthier than those who cannot. Did this study prove causation or just correlation?
Berkeley Bee (San Francisco, CA)
Of course, this key paragraph is at the end of the piece, while, of course, it should be at the beginning: "Of course, the findings in this new review are associational, meaning that they prove that people who run tend also to be people who live longer, but not that running directly causes the increases in longevity. Runners typically also lead healthy lives, Dr. Lee says, and their lifestyles may be playing an outsize role in mortality."
miguel (upstate NY)
Well said. Typical junk science with no comprehension of the difference between causation and correlation. Also, sorry to be a curmudgeon, but the point is not longevity for its own sake, but quality. Not everyone is physically or genetically suited to be a fitness fascist who runs marathons and is addicted to constant workouts to chase the endorphin rush. Healthy habits, diet, low impact moving around (like walking the dog), laughing, loving and spending time with family and close friends are all variables that the so-called experts who continuously publicize their "research" never tell us they've even considered.
Ron A (NJ)
No "junk science" here. This was a careful meta-analysis of previous longitudinal studies. It re-affirmed the first study and expanded on it. The study also correlated well with a separate study showing a longevity benefit from running.

There is no plausible way to do a random controlled trial experiment for something involving longevity with humans. Every single factor of people's lives would have to be controlled except the one you're studying for a person's whole life. That's what makes a study like this the best we can hope for. And, the evidence is overwhelming!
andruchowsteve (RI)

GusLevy (USA)
I am 46 and have run since high school. I have never gone 3 days without running a 5k in that time - my routine is to run a 5k 6 times per week and walk/hike 5-10mi at least once per week.

Having played competitive tennis, baseball, basketball and also mountain and road biked a bit, for me, there is no physical exercise that compares to running. It is the simplest yet by far most honest exercise because it is an activity that demands no opportunity to either mentally or physically coast - as a light "ball-striking" runner the difficulty in running is mostly mental rather physical from my perspective.

The physical benefits of running seem intuitive to me - I'll let the smart guys calculate the scientific preciseness of the benefits. Having said that, imo my intuition also tells me that being a runner also trains a person to mentally prepare for life's challenges as well which will ultimately will lead to longer life expectancy: Patience, persistence, fortitude, etc. are all things that being a runner helps to improve.
Tim Gulden (Bethesda, MD)
It seems more likely that only healthier people are able to run for at least five minutes, while less healthy people can not. Run too slowly and you are walking. The big problem with a correlational study like this is not so much that it omits variables like healthy lifestyle -- the problem is that it can't establish the direction of causality. The reverse of what the researchers suggest seems much more likely: is it that running makes people healthy, or that only healthy people run? The numbers in a study like this come out the same either way. Controlling for smoking and drinking does nothing to help with this.
Mary (Redding, CT)
What is the percentage of runners who need joint replacement? Not a great tradeoff in my opinion. (I'm a half-hour-a-day brisk walker whose walks almost always include uphill stretches.)

And a few people questioned whether running really added materially to people’s life spans.

insight (US)
Approaching 50, I often hear from peers that they either have stopped running due to injuries, or accompany their running schedules with frightening amounts of ibuprofen.
Beginning to experience the same issues, I tried something else.

I took off my wristwatch.

Turns out, I and most of my running acquaintances were fixated on "tracking" our performance, always pushing to keep up an arbitrary pace regardless of how our bodies were responding. The recent explosion in "tracking" apps that automatically post paces/times on peoples' "look at me" pages only exacerbates this.

Now, I run at the pace that my body tells me is good for the given day, time and temperature. I have had no injuries, and experience very little soreness, all without pharmaceuticals.
KJP (San Luis Obispo, Ca.)
Insight has it partly correct. You also can train the hard easy method where you work hard then let muscles recover. I did that for 25 years and it mostly worked very well. From 34-59 I went from one day easy then moderate-hard workout to 3-4 days easy then hard effort. As we age it takes longer for muscles to recover.
Jm (Burd)
This is the smartest comment I've read in response to this article. Run, but listen to your body.
BoRegard (NYC)
There's been a few recent studies that show that tracking-apps actually hinder peoples fitness goals and needs. For some of the reasons you cite.

As for the injuries so many "runners" suffer...most of them could be eliminated IF people would seek out an experienced running coach, or do some real research on their own and learn how to run properly for their fitness, and body type. Proper running style is crucial to avoiding injuries, and most people have a broken style.

Most people do not run with a gait that suits their body, as they develop bad habits from when they were starting out, and had to make all sorts of adjustments to their gait (like trying to keep up with a more advanced runner, too slow of one, bad advice, etc) to just make it thru the runs and early soreness, etc. They find a comfort zone and stick with it, even when they have advanced and should be opening up, or lessening their reach. Far too many "runners" bounce up and down (typical joggers form. Ex; ladies if your pony-tail is bouncing all around your form is broken.) instead of "pulling" themselves forward...gliding across the ground.
Peter Kobs (Battle Creek, MI)
Thank you, Gretchen Reynolds, for this very interesting article. I ran regularly for more than 30 years. Now, at age 58, I find it necessary to alternate between running and walking, followed by machine weights and a bit more walking for the cool down phase.

My father, now going on 92 years old, ran for decades (mostly outside) before switching to walking only at about age 62. He also takes a low-dose aspirin every day, as do I. So far, he has out-lived all of his male relatives -- father, brother, grandfather, cousins) by about 23 years, despite a history of moderate heart troubles. (Doesn't hurt that he's a retired doc in a small Midwestern city.)

Reading some of the other comments here also propelled me to learn more about Jeanne Calment, who lived to be 122 years old, setting a world record. Calment had many social advantages that seemed to contribute to her longevity (1875 - 1997). You can learn more about her lifestyle and habits on Wikipedia. Fascinating stuff!
Ollie (Missouri)
I remember the last time when this was studied, the result was that an hour of running only added an hour to your life. Now all of a sudden it's jumped from 1:1 to 1:7? I think if you were to look simply at the ages at death of runners vs. non-runners, the data would not bear this out.
BobC (Dallas)
If it is one to one their is not much real benefit. Do the math, how long does it take to run 500 miles annually. Not long. And as a fitness program, 500 miles a year is a good number.
greenie (Vermont)
More than just life expectancy, I think that years of healthy life are more important. Adding years to life that are spent in poor condition would likely not be welcomed by many. Getting to spend more time in good health would be desirous. I'd be interested in seeing those numbers, not just total extra years lived.
Mickey (NYC)
A while back i saw a study the plotted average life span vs "quality of life". I forget how exactly QOL was defined, but the graph was particularly interesting. First it showed a small increase in lifespan for those that did moderate exercise. But the two curves were very interesting. For those with little or no exercise the graph was a near straight line with a negative slope representing loss of QOL from age 30 to age 80-something when the graph touched Zero, representing death. Meanwhile the exercise line had a much less pronounced downward slope from age 30 until about 6 months past death on the other line, then the line took a sharp downward turn to zero over the following year. The bottom line was that exercise only extended life by about 18 months, but greatly prolonged Quality of Life up to the last year.
iPlod (USA)
Greenie, I agree with you. I ran track, cross country and road racing as sport only. Now decades later, I still don't view it as a means to a longer or healthier life. I do it (very slowly now) for the sheer joy I obtain and to be outside instead of working out indoors on a stationary machine. I would rather my modest running routine add life to my years rather than years to my life.

Runners were once described to me as 'healthy cripples'. I loved to run, when I was a younger man. But now the knees, hips and lower back all give me trouble. I don't think there is much benefit lost by switching to a rowing machine. Aerobic exercise for 25 minutes is pretty much all it takes to get the benefits.
RG (LA, CA)
I wish I understood the implication of "slow" running vs walking. I am a very slow runner and in various races see walkers pass me. If its the same pace/distance, why would running be superior to walking? Perhaps my slow and the researcher's slow are different concepts.
Luk Brown (Vancouver)
Thank you for this well informed article. Something that struck me is the conjecture that running is uniquely beneficial in some way compared to other forms of cardio exercise such as cycling.

I hypothesize (and would like to see this tested in some way) that the unique physiological benefits of running pertains to the impact compression exerted to the soles of the feet repeatedly that serves to encourage and maximize blood circulation to most lower extremities of the body.
GB (Alexandria, VA)
I remember a number of years ago, I read that swimming is the best exercise, and keeps your organs significantly younger.

People get a clear idea of the different levels of exercise provided by: strolling, walking, power walking, jogging, running, and marathoning. All those levels get neutralized on two wheels to a single verb: cycling. As a cyclist, I am leery of cross-exercise comparisons, especially with running, because its relative simplicity allow experimenters to select very specific participant groups and activity levels, which are invariably less well demarcated in cycling and the other activities mentioned in the study. Moreover, Lee et al. used data from a different pre-existing study, the Aerobics Center Longitudinal Study, for their comparison of running with other activities. Until I see an explanation showing the comparability of their methodology with this one by Lee et al. (Interested, Ms. Reynolds?), I will withhold my belief in running as the emperor of all exercises, and stick with my bike, which, after all, has the added advantage of getting me around town faster, farther, and more presentably than running could.

I love how running makes me feel, and I love the places I can explore on foot or on bike, and I never want to be the sedentary cynic who posts responses to stories like this one with comments about Jim Fixx.

Diet and exercise. A few months ago the Times published an article saying that there is no "one-size-fits-all" diet - the "best" diet for someome depends on the person. When will the Times realize that the same is true for exercise? While exercise is undoubtedly good, there is no "one-size-fits-all" exercise that is best for everyone - it depends on the person. Meanwhile, the number of contradictory studies published on these pages is staggering.
Norton (Whoville)
Absolutely agree about individuals and exercise. The thing I hate about these studies and subsequent articles is that there is no one right way to exercise, especially if genetics is not on your side to begin with. All these articles do is bring out the smug "If you don't exercise a certain way, you're just plain lazy" attitudes. Enough already. No exercise is superior if your genetics get in the way and/or you're in pain the whole time you're doing some specific activity.

And how many hours of ones life are wasted running? I guess it all depends on ones outlook, perspective, ability and physical condition. In the 70s it was reported that eating peanut butter would shorten ones life. Then eggs etc etc.... Then later there was this report that said buying milk in plastic containers wasn't good because the light caused nutrients to be depleted. Better (the article said) to buy milk in paper cartons. It was later discovered that the writer held stock in the company that made paper cartons. Makes you wonder if running shoes will now fly off the shelves.

It seems to me that this actuarial-type approach that focuses on longevity and 'return on workout investment' overlooks quality of life issues. I did triathlon for 20 years, because it was challenging and lots of fun. Now, at 63, it's masters swimming competition and wilderness hiking daily with my dog. These are also intrinsically enjoyable. And I feel good. I could lose the 'longevity race' at any time to illness or accident, but I do not choose to enter that race ;-) Isn't longevity mostly based on genetic factors? People like to think it's their particular sport or diet, but I have my doubts.

I run 6.2 miles every other day on a treadmill. I started running in my 30s and have done it sporadically through to age 64. For some reason, I love the sport and when I'm coasting along and really hitting my stride with music streaming through my headphones, it's like riding in a convertible with the top down while your favorite song is playing on the warmest, sunny day. I realize these results are associational but after all the things I've heard about how running can be hard on the body (used to run outside but too hard on my joints now), I'm glad to hear it can be a good choice.

I run because I like to run. I find joy, relieve stress and get to be outside. Also it makes me sleep better and generally feel better. I'm not sure I care that it might allow me to live longer.

Attention needs to be paid to the impact of training over time on joints. I was sprinter and hurdler in high school; played lacrosse in college and rugby football into my mid thirties. Continued running for fitness until my fifties where became clear that my joints could no longer take the pounding. The upshot of decades of training is that now that I'm in my late sixties I'm in need of joint replacements in both knees as well as ankle surgery. Cycling is my last form of pain free locomotion and for maintaining fitness. There is definitely a physical cost to intense amateur athletic activity, especially running. I can only hope that the intensity earlier in life will continue to yield some portion of the benefits in longevity suggested in the article. I have my doubts.
gschultens (Belleville, ON, Canada)
Yes, runners live longer. This is a multi-faceted outcome, and many variables are involved, besides running. Given that, however, running also improves mood and general feelings of well-being.

I don't run, as it would be hard on my 73-year old joints. However, I do have a stationary bicycle in my basement and ride vigorously most mornings. I notice that I have more difficulty sleeping when I go 3 or 4 days without this exercise.

So, my recommendation is to keep running/bicycling if you already to this, and to take up one or the other if you don't. Even if you are in poor health, at least get out and walk regularly, working up to higher levels of exercise as you are capable.

There will alway be articles about "new research" "new findings" and "new discoveries" it is up to us to use sound common sense to do what individually we find best works for our spirits and bodies as they function in unison hour by hour, day by day. Running is beneficial. For those who can do it. I run/jog/walk and repeat when I go out for say 30 or 1 hour to do some cardio. It is about lifting my spirits, helps me fight depression which I suffer from greatly. I started running when I was 17 now in my 40's still doing it. Did it to just clear my head, help me out. I imagine many do it for similar reasons. The biggest key to success is consistency, there are day when we do not want to be outside jogging, running, power walking but those are the days when we should be outside. If not for a 20 or 30 minute jog walk. Life is so short, unpredictable, people will live until say 70 exercising their entire life and people will live until say 70 not exercising but keeping busy. I think if you workout just because you want to look good, you will get burned out and seek out another form of exercise or stop all together. If you exercise to feel good, mood enhancer that so happens to encourage better eating habits, sleeping habits, mental sharpness, your relationship building skills, personal relationships, they you are on to something.
Charles Nash (So. Cal)
I prefer more miles using a mountain bike than running. Same benefits without pounding feet and joints. Biking up steep hills is more of a workout than running and in a shorter timespan - if being productive at something is also important.
Terry Lee (North Pole)
Runners out live no one, period. Statistics prove that runners only live to be about 67 yrs. All athletes die usually under 70 years old, moderate exercise, good diet is far more beneficial to humanity, No runner has ever out lived the 90 year old housewife, or the hard working, beer drinking, cigar smoking 89 year old brick layer !
JLC (Seattle)
That is a truly ridiculous assertion: "No runner has ever out lived the 90 year old housewife"?

Who says they aren't one and the same? Have you ever been to a fun run? There are plenty of 80 and 90-year-olds.
Dv/dx (México)
"if in order to reduce your risk of dying by a year, you had to spend the equivalent of a year’s worth of time on the trails or track, producing no discernible net gain?"

As a runner, I am always interested in these kinds of studies, but by the same token I couldn't care less about the findings. The quote above implies that the only reason people run is to get some sort of increased longevity benefit.

I run because I love it. I love to feel my feet hitting the ground, my body in movement. I love to breathe deeply of the morning air and hear the birds sing. I even love to feel that extreme fatigue and anaerobic breathlessness as I struggle to cross a finish line.

Maybe I will live longer or maybe I won't. All that matters to me is that I can continue to run until the end arrives.
hen3ry (New York)
I used to run but injuries forced me to stop. Now I swim and I've found that swimming keeps me limber and helps with my sinus infections.
TSV (NYC)
Good luck to all those running the daunting 26.2 miles in Boston on Monday!
Rex (Oregon)
Thanks TSV, I'm running it on Monday at age 69, my seventh time since age 41. My level of difficulty at getting qualified for Boston has remained about the same over the years. My satisfaction with the sport has steadily increased.
Steve (The real world)
Jim Fixx should have read this.
unclejake (fort lauderdale, fl.)
smoked too much
t (la)
Jim Fixx had a family history of heart problems. He died aged 52, while his dad died aged 43. So what was your point?...
zugzwang (Phoenix)
He died from a cardio problem that he knew about. His genetic predisposition for heart problems and other previous lifestyle factors may have caused his heart attack.
R Henry (LA, CA)
Didn't quite work out for Jim Fixx, did it?
Doc Who (Gallifrey)
If Jim Fixx hadn't been a runner, he would have died at 23.
Tessa (<br/>)
At what age might Mr. Fixx have died if he hadn't been a runner?
eliza (San Diego)
Jim Fixx died of a heart attack at 52 despite his dedication to running, but his father died at 43 of the same thing. You can't totally neutralize genetics but I'd say it worked out pretty well for Jim, all things considered.
Hedy Cerwinka (Bala Cynwyd,PA)
Is there a specific age that constitutes the end of " PREMATURE" death?
Kip Hansen (On the move, Stateside USA)
My death will be premature whenever it arrives.
Mike (San Diego)
I don't like the math:

"expect an increase in life expectancy of 3.2 years, a net gain of about 2.8 years" Huh? So, what? While we're running we're not alive? If running is so repulsive to you, save your years and don't do it!

I like running. I feel most alive when I AM RUNNING. I know a lot of RUNNERS who feel this way.
BWF (Great Falls VA)
Mike is right. If you don't accept a causal relationship between running and longetivity, then run just for the opiate brain chemicals. β-endorphin, for example, has more than 15 times the analgesic potency of morphine. Yet your body makes this substance naturally and legally, and for the low, low cost of a bit of sweaty fatigue, when you run. You've heard the saying, "Nothing tastes as good as being thin feels?" Running can be a chore, but the healthy feeling afterward is worth it.
JS (Detroit, MI)
hhhmmmmmm.......hey Gretchen...how'd that running thing for Jim Fixx ??
clark kent (charles town, wv)
I guess ignorance IS bliss. Jim Fix died from a heart problem, not from running. Try to educate yourself BEFORE you post.
CK (<br/>)
You can look it up: Jim Fixx took up running because he was a heavy smoker, very overweight, and had a family history of premature death from heart disease. Running clearly prolonged his life.
Kip Hansen (On the move, Stateside USA)
The true Bottom Line in this study (kudos to Gretchen Reynolds) is:

"Of course, the findings in this new review are associational, meaning that they prove that people who run tend also to be people who live longer, but not that running directly causes the increases in longevity. Runners typically also lead healthy lives, Dr. Lee says, and their lifestyles may be playing an outsize role in mortality."

Running does not cause increases in longevity.

People who get their 20-30 minutes of moderate exercise more days than not
are getting 90% of the benefits available from exercise -- if you want that extra 10% and have the time and inclination, and your doctor agrees that running is Ok for you (it is not for everyone -- it tends to be high impact) then enjoy.

Just don't be fooled by this kind of madcap faddish epidemiology that you are "adding years to your life".
Brian (Canada)
I ran for 40 years, and it certainly kept me fit and trim (I was not a long-distance runner but ran fast, eg. a sub-39 minute 10K into my fifties. But I suspected the 3X a week runs were causing my leg and back pains, and have substituted walking (vigorously), weight-training, a little swimming, and cycling (in season and vigorously). Will I die earlier? I think other factors will decide that. In the meantime, while I've doubtlessly lost some aerobic capacity since quitting running four years ago, I have fewer aches and pains now and don't need to buy running shoes. And weight training does make my abs look more impressive.
SVO (<br/>)
Mr. Hansen's "true Bottom Line" is an important caution, but why should we thank Gretchen Reynolds for saying this at the very end of the article? Until that point, the entire article shows magical thinking about correlational data delivering causal conclusions.
John (Dallas)
Well there's this: "Why running should be so uniquely potent against early mortality remains uncertain, Dr. Lee says. But it is likely, he says, that it combats many of the common risk factors for early death, including high blood pressure and extra body fat, especially around the middle."
Dave (Richmond, VA)
Uh, that depends on heart health. If I ran for an hour, I would die before the hour passed. Please some of us have had heart attacks and our hearts cannot function well.
PaulN (Columbus, Ohio)
Technically, if you ran for an hour and you died before the hour was over, then you would have to deal with a contradiction for the rest of your life.
Ruth Meyer (NYC)
Very confusing. In the "Blue Zones" of the world, (Okinawa, Sardinia, etc.) NONE of the centenarians there today ever ran for an hour a day or a week. They were active, engaged and their diets made most of the difference - oily fish, olive oil, soy, red wine, etc. Jeanne Calmet (sp) the French woman who lived to be 120, smoked, ate a lot of chocolate and hardly did any exercise. Exercise is very important, but for those who don't run, like the centenarians, it seems not to matter at all. Americans are fixated on no-gluten, no dairy, no this, no that, while centenarians worked hard, ate to their heart's content and relaxed.
Miss Anthropy (Jupiter, 3rd Quadrant)
Actually, Jeanne Calment lived to be 122.
Ralph (Michigan)
The New York Times obituary dated August 5, 1997 reported she was born Feb. 21, 1875. “She played tennis, took up roller skating, bicycling and swimming and took great pleasure in joining the hunting parties (her husband) organized. She also studied the piano and enjoyed the opera. Mrs. Calment rode a bicycle until she was 100 and walked all over Arles to thank those who congratulated her on her birthday that year.”

No cars in 1875, so she likely walked around the community (to stores, friends, etc.). The world then did not have the modern labor saving devices we take for granted. Very few of us walk to the store for food anymore. A sedentary lifestyle was not an option then for most people.
Garbo (Baltimore)
In Okinawa and Sardinia, the Centenarians, walked everywhere, didn't have a lot of dairy, and didn't eat a lot of this and that, didn't eat processed foods.
Jim Strawn (OH)
Always amazes me. I run. But the fact is that people who get up and run every day probably do many other things that are relatively healthy, like sleep for example. Correlation/causation error is so common.
S. Reader (RI)
What you're describing is more of a need to control for certain variables including confounding variables, not mixing up correlation and causation. The Times often has a problem with the latter as well, though.
Sam (Virginia)
No one ever mentions the fact that runners experience a of comfort and health as a result of running as opposed to nonrunners almost as if you are 10 years younger than you really are this is worth more than any minute toward longevity
Brian (Canada)
Not sure about that. The four nonagenarians I know were never runners.
Ounceoflogic (KY)
Back to running now is it?
After all these years of fads and research reports shouldn't there be at least a few non-smoking, vegetarian, yoga doing, one-glass-of-wine + 5 gal of water a day, tennis playing, fit-bit wearing runners out there in their 150's?
Michjas (Phoenix)
The physical benefits of running are secondary to me, Don't get me wrong -- a good run is satisfying just like any hard work. But what is different about running, and is almost always true, is that it benefits my mood and gives me a sense of well being. If I had to guess, I'd guess that the psychological benefits of running are a big part of any overall improvement in life expectancy.
Meredith (NYC)
Yes. Same with aerobic dancing to music you love. A key to well being.
Haudi (<br/>)
I get the same boost from my Nordic-walking -- about 4 mph, 20-30 mi./week. If my schedule or the weather interferes for more than 2-3 days between sessions, my wife says that "Mr. Grumpy" has returned. Bottom line, I do it 'cause I love it.
Pat Boice (Idaho Falls, ID)
Michjas - the old endorphins addiction! I'm joking - a bit - about the addiction but I do have family members that run and it's like my morning coffee to them - I need it!!
Frank Perkins (Portland, Maine)
It is always nice to read somewhere that something you are doing anyway is a good thing to do for improved health. I have been running/jogging for 58 years and estimate that i have circled the globe 2X. Looks like i have my 3 years in the time bank.
APLawyer (Outside DC)
These findings are nice, I guess, but I run because it makes me happy, not to live longer (or even to look better).
Monk G (South Of Most)
I'm a runner, so I celebrate this news. However, I wonder if they considered the "Blue Zones" work from Dan Buettner? Most of those people weren't runners at all but walkers. It seems this research, while promising, is incomplete.
Leslie (Long Island)
I would rather die earlier than run.
Anonymous (n/a)
The problem with this widespread idea is that exercise (and staying slim) are good ways to avoid long declines, both physical and mental, before they death. (This is called "the compression of morbidity".) Both exercise and weight control are also good for the brain. Who wants to spend years wracked with aches and pains -- or go demented -- or both?

That's what you say now!
Jeffrey Gee (Roanoke, Virginia)
Unless you aren't paying attention and run out in front of a bus and are crushed to death. Then, your life expectancy will be just as long as someone who lazily walks in front of a bus and is crushed to death! Just saying…
Marie (Highland Park, IL)
The most interesting statement in this article is this: "Of course, the findings in this new review are associational, meaning that they prove that people who run tend also to be people who live longer, but not that running directly causes the increases in longevity. Runners typically also lead healthy lives, Dr. Lee says, and their lifestyles may be playing an outsize role in mortality."

I suspect runners may also be better educated and may belong to a higher socio-economic class, which are both associated with longevity.

In other words, this article is somewhat misleading because I see no reason at all to believe running would add even one hour to my lifespan.
Doc Who (Gallifrey)
More than somewhat misleading. Just as a half-truth is considered a whole lie...
But everyone knows that running is good, so that's the take home lesson.
Benjamin (Childers)
As an activity with a very low cost associated with entering (a pair of decent shoes - $30 at Ross Dress for Less), I would think that running is ubiquitous across SES
Marie (Highland Park, IL)
It's got nothing to do with cost. Working class individuals probably get enough exercise (though they don't call it that) by doing such things as cleaning house, doing house repairs, maybe gardening (at least that's what my parents did). Richer people can hire others to do that kind of work for them. Then they get exercise (and they do call it that) by joining the gym or mabe even by running.
Tom (Mclean, VA)
So if you run four hours a day you'll live forever?
Doc Who (Gallifrey)
Yes. Studies show.
Jane (Providence, RI)
A few paragraphs into the article: "Improvements in life expectancy generally plateaued at about four hours of running per week."
JD (Anywhere)
At least it will seem that long.
Robert (South Carolina)
But when running strains your knees, hips and back and you can no longer run because of the pain, you might have a tendency to vegetate, take NSAIDs, opiates etc. Then you lose that exercise effect. You can try switching to other forms of cardio if they don't also hurt or are readily available.
Sisyphus (GNV, FL)
Good running form can mitigate strains on your knees, hips, back [etc]. Get a good running coach and work on your form. I am 62 and have fewer aches and pains running than ever and I have been running since for 50 years. Short strides, high cadence, pick your feet up and keep them under your body...and live longer.
Benjamin (Childers)
I would push back on your comment in so far that if you are having that many issues from running - you are probably not running correctly. A lot of seasoned runners wear the wrong shoe, have poor form, and don't train appropriately. I would take the time to be fitted for shoes, work with a coach to improve your form (especially foot strike), and cut pace and miles to find a place where running is both enjoyable and beneficial.
Brian (Canada)
See my reply above.
Jaque (Champaign, Illinois)
Dr. James Fries and his colleagues have done the most comprehensive studies of effect of running on life extension, but more important he proposed the idea of "Compression of Morbidity" in old age. I don't know why rehash the same old research again and again. See the research here:
