Pulling the plug before 60? Where do you live that everyone over 60 is on death's door?
I'm reasonably well past that and there a whole lot of us and we're still going strong. I swam an open-water 10k at 63 and am planning another for my 70th. I'm working on breaking 4:30.
A neighbour finally stopped competitive cross country marathons last year at 75. He's not retiring from cattle ranching until he's 80. Cattle ranching around here means horses, roundups, roping, branding, fence maintenance, etc. Not for the faint of heart or weakness of mind or body.
Another guy, at 94, was up and down a ladder repainting his house. Nobody blinked an eye.
30 years ago, I ran a free introductory programming course through a community association. Ages ranged from 12 to 83 and most of the class was over 60.
That's just neighbours, not any kind of "old and bold" club. Sure, the care homes are overflowing, but that's a supply problem, not a demand problem. Only a relatively small fraction of people will ever see the inside of such a place, except to visit someone.
