It's a nice "just so" story, but when you're in your 80s, you are already in multiple stages of decline across the board. One small injury can cause a cascading failure of systems.

I don't know how you can so authoritatively state this about a man in his 80s. (e.g. - past the average life expectancy). 80 is just really really old. How fast the decline gets you at that point is really mostly a genetic lottery.

But if the anecdote helps you be more active personally - more power to you.

"how you can so authoritatively state this" => because that is the exact order of events :) A happened. Then B happened. i didn't say A caused B. just like we're all discussing here in this thread. just another datapoint that we are sharing here where it seems like there could be a causation not just correlation. but i didn't authoritatively state anything other than I know what happened on one date, and then what happened on another date.
