When I used to be a personal trainer, an older lifter (in his late 50's) who was in great shape used to talk to me all of the time. He and his wife were both avid lifters since the 1970s. She was still in phenomenal shape as well.
He used to always joke with females in the gym to "stay away from that guy. He'll break your heart"; which usually worked as a great introduction.
One day he says to me: "Kid, things change as you get older. You've seen my wife. She's pretty now, but you should have seen her body 25 years ago! Back then, all I wanted to do was have sex with her. Now, my priorities have changed. I don't know which I'd rather do; my wife or have a really good shit."
I laughed and said: "I hope it is a long time before that choice takes me more than a second to choose."
"Kid, it comes sooner than you think."
