“68 is “elderly”?” Got my attention too. I’m a couple months from there. There is different elderly for sure.
Couple weeks ago I pulled 20 4” round wooden fence posts & 4 4x6 square posts stuck 3’ in the ground, out of the ground, by hand. Not saying I wasn’t sore.
(the 4x6x8’ were pretty scary, had me huffin & puffin good)
I couldn't match you on the posts, no doubt, but ride dirt bikes and mountain bikes and can run up many flights of stairs.
My mother just entered an assisted care at 97, but I've noticed many residents there who are only around 70 and seem older and more frail than her. I feel badly for many of them. Life can be too short sometimes.
