Well, there's this beautiful 18 year old girl I know, and my 35 year old friend saw her and was wowed. Then he said he's about old enough to be her father, and he's only six years older than me. That put things in perspective, but this is all new to me.
While I don't consider myself old, I've already figured out the worst thing about aging, and that's wishing that you knew then what you know now. The best thing about aging is actually being wiser.
