My doc told me recently not to think of myself as old. I'm 66---and yes, things are starting to show my age--such as arthritis, gray hair, wrinkles, etc. And a new knee. It's nice that these things have been happening rather slowly and not all at the exact same time.
I do think we shouldn't dwell on all these changes, but do the best we can each day. Hang in there, Aviza.
