My great aunt golfed until about 95, danced, read books, went to a cafe every day. She bad a wonderful life and was very happy right until the end. 80 is way too young for the kind of physical and mental degeneration you’re envisioning to happen automatically. Now most people don’t eat well, aren’t especially mobile, will be quite overweight by 60+ with multiple chronic health conditions, lots of muscle loss, etc. This is obviously common. My point is most of those conditions are lifestyle conditions and are not automatic features of aging.
