At 82 I'm well past my sell by date. And I have my share of chronic conditions. I do see a doctor unlike my 87 yo neighbor who retains much health, but her mind is now wandering a bit. I've survived the removal of parts that I can "live without" - but that has consequences as well. But you are right, I don't exercise as much as I need and witness the strength decline as a result. The workout have never been fun and the gym being closed hasn't helped nor has that stupid mask stuff helped - great excuses of course.
