It's kind of like the old joke:
Why do dogs lick their balls?
Because they can. (Didn't say it was a GOOD joke)
A 60 y.o. man has his choice between bedding a woman his age and a 20 year old. Hmmmmm, he'd probably have to think for a nanosecond or two there.
However, if you're talking about a long term relationship where meaningful conversations become an issue, then things are a bit different. Hearing the word "like" 4 or 5 times each sentence gets really old.
