Thanks for sharing this.

I had to smile when you mentioned sounding like you're 80-something because, although I'm not 80-something yet either, I'm a whale of a lot closer to it than you are.

I can relate to a lot of what you wrote. Of course, for me, it's all mostly in the past now except for the residual effects... which are surprisingly still strong. (I'll spare both of us the details... to the extent I can even remember a lot of them!)
