But again, remember, our ancestors weren't like running marathons, you know, they were, you know, occasionally running, they were mostly walking, they were carrying, they were doing things that don't cause injury that a lot of the stuff that we do today that causes injury is because, you know, you get weekend warriors who aren't really all that fit there, you know, they're, they're, they're, they're not, you know, prepared for the stresses that their body

then encounters and then of course they overdo it and then they get injured. But that's again a kind of weird modern way in which we exercise. And so what is your general prescription for exercise? I think we can say a few things. The first is that always some is better than none.

You know, if you just get just a little bit of physical activity every day and you just look at the outcome of that, it has enormous effects on people's health. It increases people's longevity, it decreases their vulnerability. to a wide range of diseases. And that curve continues, right?

So for example, on average, for most people, if they exercise about 20 minutes a day, which is 150 minutes a week. And it can be just like walking. It doesn't have to be running. That can decrease your overall life history, your longevity by about 30%, and reduce your vulnerability to a wide range of diseases enormously.

And then the curve continues to go down, and then eventually it kind of tails off. um and so if you do anything more than an hour a day you're not going to get any more benefit from doing an hour and 10 minutes a day or two hours a day or whatever so so basically the answer is that some is better than none more yields greater benefits but those benefits begin to tail off

And then, of course, there's variation in the kind of exercise that you do. I mean, you know, are you running? Are you walking? Are you doing strength training, you know, weights, etc.? And the answer is, you know, mix it up, right? You know, it's good to do a little bit of strength training, especially as you age.

But it's also, you know, aerobic physical activity is really important for kind of your base core, your fitness. You know, some kind of mix is always kind of important. But there's no one prescription. There never will be.
