That’s awesome! The benefits of exercise against aging, mental illness, etc are numerous and well documented. Everybody should do it.

If that was true athletes would be the youngest, mentally healthiest, and in many other ways better than average. But that's not the case if you look at them. My guess exercise is beneficial only to some level, after that it has a big toll on everything. Including IQ, mental and general health, and so on.

Can exercise make the face look younger? Or the body? Is exercise the best makeup? ;-)

There seems to be abundant evidence that exercise is often the best solution for any number of things. The problem is that doing it sucks.

Kettlebells are the perfect middle ground for me. Dynamic movements, easy to incorporate strength gains, very little floor space required and one kettlebell is enough to get started. After a few years of kettlebells I feel like my lower back is made of titanium.

Downside is there is a fairly steep learning curve to use them without injury.

Neat study, but I always chuckle at these, because has there ever been verified science that shows exercise is unhealthy ? (besides overtraining) The general consensus should just be exercising is good for you, that's it, done.

You could look at the inverse: Not exercising causes the brain to look older. Knowing all of the ways not exercising is harmful is probably a good thing.

But I agree, it would be better if everyone exercised!

It is the case, actually.

Here's another study, although for some reason it's 95% male, it shows athletic men live an average 3.5 years longer. It also shows athletic women live 0.7 years less, but due to the low number of females in the study I wouldn't read much into that.

Find a better way of exercising. There is something out there that suits, surely. Sometimes it’s just a step removed.

And importantly: stick with it for a few weeks before deciding whether you enjoy it. Virtually no one falls in love with the gym (or whatever fitness activity) the first time they walked in. Getting started isn't always fun. But over time it can become very rewarding.

> brains that looked nearly a year younger Seems like a pretty small effect - if I'm 58 and I have the brain of a 57 year old, and to achieve that I did an entire year of exercise (as was done in this study) ... you'd have to evaluate it against many other things to decide if that was really the easiest way to achieve that result. I'm always suspicious of small effect sizes even when they are statistically significan…

Many such effects compound with time, and every additional year of regular exercise adds compounding benefits in multiple systems across the physiology.

Running makes you look older, unfortunately.

Cycling too. The standard being 20kgs under weight, skin baked like old leather, and a previously broken collar bone. But, nothing beats it.

Wear sunscreen? It's necessary to not age fast if you go outside often. And moisturizer and retinol if you'd like too.

I think this can be bad advice for people who may be predisposed to dislike exercise due to past experience or just straight up unfamiliarity.

More constructive is to think about what you don't enjoy about the activity and whether those are intrinsic qualities or can be changed. If they can be changed, change them.

Similarly, it's a good idea to think about things you know you enjoy that can be coupled with exercise. Add those things to your exercise environment to build up positive associations over time.

As a simple example: if you feel self-conscious about your body when you go to the gym you shouldn't try to just suffer through that feeling. Just workout somewhere where you don't feel self-conscious.

I wish it were that simple. I’m of Scottish and English genes. I wear spf 50 and still get burnt in the savage New Zealand sun.

I try to go early.

Nonsense. Running at an Olympic level and pushing the boundaries of what we've evolved for might leave its mark. But that is not what is being talked about here.
