Who's hand?

I used to love my hands. Not in a "I want to marry them" sort of way, just that they were strong, distinctive and served me well. I used them to fix plumbing problems(for 30 years), build and repair houses, play guitar and make art. Now mostly I make art with them. As I've aged I look at them and wonder, now who's hand is this? Sometimes they look like my mother's or father's, not mine. And especially in this shot, I notice, it's so damned old looking. 57 years of movement, hoping they keep working for a long time.
