After you reach a certain age I think you need to avoid certain activities.
Forget that weekend softball game type stuff.
This is where we disagree to a point.
Weekend softball only leads to injury if you're not training properly.
I probably played about 50-60 games of baseball last year across three leagues, without any injury related to age or conditioning. I probably ran close to full speed hundreds of times, including dives, slides, jumping, etc....
I have seen guys up to a decade older than me playing hard as shit.
Does the risk of injury increase as you get older? Without a doubt. Do they take longer to recover - f yes, but you can mitigate and still do most things if you put in the work in a sensible manner.
