By the time I get 90, I figure there is a good chance that all my friends and relatives will be gone. Who wants to live alone in some old nursing home being treated badly. Obviously, this man is more the exception than the rule. I would guess genetics plays a big part as well. He may have also taken really really good care of himself when he was younger, something that most of us don't do. Nope. I'll pass. I figure when I get 90 I'll be of no more good use to anyone or myself.
