I have seen that already too. Watching it again with my son’s mother-in-law and again with an associates in-laws.
I have a fear of outliving my my usefulness or ability. It is a conundrum you probaby can’t out think so you just do the best you can every day.
I think one way of dealing with that is to go out as naturally as possible.
For those who believe living should not include becoming a burden on others while existing with no hope of rejuvenation, go about life as normal relying on painkillers and nothing else.
There will come a day when I will go mushroom picking for the first time...
