Do you think hooking up is mostly a college kid activity or does it happen elsewhere just as much?

I was at a presentation today by someone who studies the sexual behavior of college kids. She was talking about hook-up behavior. She seemed to think that the hook-up was primarily something that college kids do.

People who don’t or can’t go to college tend to get pregnant more quickly and don’t seem to have time for hook-ups. Older people (about 30) are married. I’m not sure what happens in the time between college graduation and marriage.

So what do you think? What is your experience? Do you or did you hook-up in college? What did you do, relationship-wise, between college and marriage? If you didn’t go to college, did you do any hooking-up? What is your definition of a hook-up?

What’s your perception of the general trends in society—working people, college kids, post-college population and older population—with respect to hook-ups? What about the retiree population?
