I note that only two responders are chronologically older than I so far.

Like Robyn, I feel like a teenager...from the chin up. It's what's below the shoulders that's breaking down. Some days I feel about 90, but than I subtract my mental age. That brings me to my actual age of 71, and getting older each day.

BTW, when I read, today, of the passing of David Nelson (Ozzie and Harriet), I did have a brief pang of old age creeping up.
