You don’t have to know much about me to know that the latest video from The Bioneer on training for longevity is like catnip for me:

You will not be surprised to learn that the advice comes down to move more, move more diversely, and learn a lot. (Of course, adding diverse complex movements is learning.) But there is also specific useful advice re: power, bone density, tendon strength, etc.

I have long made it a general practice not to blame my age for any declines or limitations in my capabilities. It’s not that I don’t think my age matters. It’s just that I can’t do anything about my age, so blaming it doesn’t seem useful.

I now realize that I’ve been enabled in this by the fact that I spent my 20s, 30s, and 40s as a sedentary office worker. I did “exercise” some, but not a lot, and not very effectively.

The result of that was that when I finally started making exercise a priority in 2008, I was improving my fitness from a pretty low level. That meant that all through my 50s I was able to report, pretty much every year, that I was in the best shape of my life. (It was in 2014, when I was about 55, that I initially reported that I was getting enough exercise. A year and a half later I wrote this somewhat smug post on the myth of age-related illnesses of middle age. (I tried pretty hard not to be too smug about becoming fitter all through my 50s. Smugness is never very attractive, and it definitely doesn’t age well. I think that post holds up okay as being not so excessively smug.)

Looking back on it, I think my conclusions were the result of having a pretty skewed picture of what sorts of improvements in physical capability can be expected in an “older” person, based on have started from such a low base. Based on my experience these last two years, I’m beginning to think that I’ve made about as much progress as I can expect to make.

That’s not definitely true. I continue to exercise. I continue to seek out new modalities of exercise. Maybe one of those will yet do great things for my physical capabilities. And it’s still true that I’m in the best shape of my life. But for the first time in a decade, I’m not in better shape than I was a year ago.

Still, I think I’ll hold off on blaming my age, at least for a while yet.

When I was a kid or a teenager, my skin would heal from minor scratches almost immediately. A scratch (like from walking through brambles, which I did all the time) would heal up in maybe a day and a half or two days. Then, sort of all at once, when I was about 24 or 25, suddenly it took twice as long. I noticed it when I was living in Utah and hiked a lot in the mountains and deserts, and would get similar scratches, which would now take three or four days to heal.

I figured I was just getting old, and it would just keep getting worse. But it did not. Instead, it stayed like that for thirty-five years. However, just in the past year or two—since I reached my 60s—I’ve observed a fresh doubling in wound-healing times. Now a minor scratch takes a week to heal.

The surprise here is not that the speed of healing declines as one gets older, but the weird stepwise nature of the change—stability for decades, and then an abrupt doubling in time to heal.

I don’t know if that will continue. Maybe I’ll continue to heal at this rate until I’m 105 or so?

I’ve documented this largely for my brother, who once expressed appreciation for the fact that having an older brother gave him a four-year heads-up for this sort of age-related change. (I’m not sure he appreciates it as much now as he did in his 30s and 40s.)

I looked for some research studies as to whether my observation points to a more general phenomenon, but wasn’t able to find much. My brother found a study, which says in part:

The rate of epithelialisation appears to be different in older persons, but the magnitude of the delay may not be clinically important.

THOMAS, D. R. Age-Related Changes in Wound Healing. Drugs & Aging, [s. l.], v. 18, n. 8, p. 607–620, 2001. DOI 10.2165/00002512-200118080-00005.

I guess, as long as you do eventually heal up, the length of time it takes is “not clinically important,” but it’s still kind of a drag to be wounded for week(s).

The sort of scrapes that are now taking longer to heal than they used to.

It’s also sad not be of an age to think, “Oh. I could practice and get good at that.”

My brother

I’m meaning to write something about rejecting this thinking. I’m constantly thinking, “Oh, well. Maybe if I’d started that in my teens or early twenties, there’d have been time to get good at that thing.” But this is crazy talk on many levels. You can only get good at so many things (is one level). But based on the age of my (both still living) parents, there’s no reason to think I’m not going to live for another 30 years. When I was in my early twenties, my time horizon was way shorter than 30 years.

There are a lot of skills that it might take three years of steady effort to get good at. (I’d guess that drawing is one of those.) I could do TEN of those in the time I’ve got left.

Starting with sedentary mice aged about 65 in mouse-years, half were put on a program of high-intensity interval training:

the interval-trained mice seemed in many ways younger than they had been at the start. In particular, they were stronger; when pulled backward gently by researchers, they would cling to a bar longer than at the start of the study. They also had greater endurance capacity, as well as more muscle mass in their hind legs than the sedentary animals, and they scampered faster. Few now were frail.

A friend of mine posted to her Facebook page recently criticizing a whole category of ageist comments along the lines of “You’re only as old as you feel.”

It caught my interest in particular because I’d been mentally composing a post about how I just turned 58, but I’m not suffering the aches and pains that supposedly go along with getting old. My friend’s post reminded me that referring to this as “feeling young” is problematic. And yet, I find that I come down on the other side of this issue. Sure, there is a certain irrefutable accuracy to say that your age is the current year minus your birth year, but age is many things besides a mathematical calculation—at a minimum it’s a social construction, and also perhaps a collection of biological circumstances.

It’s true that what I mean—and what perhaps I should say—is I feel good. Better, in fact, than I’ve felt in years. I’m stronger, more flexible, and more agile than I’ve been in longer than I can remember. I move with more ease, more power, and more control. I have more endurance. I’m certainly more comfortable in my own skin.

A lot of this is just good luck, of course—good genes, avoiding serious injuries and serious illnesses so far.

Beyond good luck I credit my movement practice for most of the rest. Taiji. Walking and hiking. Running (merely an adjunct, but one I enjoy in particular). After years of lifting with machines to little noticeable effect I now do almost all my strength training with bodyweight exercises and am having much more success. (The main exception to pure bodyweight exercise is doing kettlebell swings for my high-intensity interval training, which I ought to write about because it seems to be doing some good, and is also quick and fun.) Push hands I wrote about recently. Animal movement ditto. So new I haven’t had a chance to write much about it yet, I did yoga for the first time last week.

But to bring this back full circle, I’m not so sure that it’s wrong to talk about “feeling young.” My friend is right—growing old is a privilege not everyone enjoys. It is indeed better than the alternative: dying young. But just as I can see her objections to denying age (as if refusing to acknowledge it meant something), I object to denying one’s felt experience. If someone says that they “feel young,” does an appeal to mere arithmetic justify correcting them?

Certainly I am not the only person to feel this way. There are always people trying to express health and fitness in terms of age. There are websites that will suggest a guess as to your physiological age vaguely based on your weight and your activity level. Various practitioners of various disciplines will measure specific things ranging from your maximum heart rate to the length of your telomeres and use the results to calculate a biological age.

They’re all pretty dubious, but I find that I do not object in principle to thinking and talking about concepts like health, fitness, and vitality in terms of age. Even though there are many unhealthy young people and many old people who are fit and vital, I think the notion resonates in a useful way.

As for me, I feel good. I also feel younger than I’ve felt in years.
