What do adults do for fun?

I am just curious what adults do for fun. Based on my friends’ facebook posts (btw, most of them are professionals – accountants, doctors, lawyers, etc.), they seem to be drinking and partying all the time after work. Those who have kids play with their kids and go places with their kids.

What do you or people you know do for fun? Is drinking really a big part in the lives of you and/or people you know?
