A Reason We Age

I will be 58 later this year. Aging has been weighing heavily on my mind for some time now. Or should I say that I'm getting in touch with my mortality? Either way, I think I have come up with a reason we age. As an elder we say, "F*CK you!!" We say "F*ck YOU!" when we're young. So a reason we age is just to get to say F*CK instead of YOU.
