My dad is 82. Up to a few weeks ago, he was going on his 3 mile daily walk, etc. He's getting better at playing bridge. He has a medical issue now but treatment may get him back to "full" activity (up to 4 or so years ago that was a 3 mile run, and that's probably off the table forever).

I don't know that he's enjoyed the past year because of COVID not letting him do very much at all, but if not for that, he'd have been golfing, etc, and scowling at the younger people driving carts instead of walking with their clubs :P. I think he has a decent life.
