I was out with some friends tonight, all in there mid 30's. after the bar closed they went over one friends house to play beer pong. They do it every weekend, they drink untill they pass out around 3 or 4am. I stopped playing drinking games in my mid 20's( I'm 38 ). I'll go out to a bar for a few beers every once in a while now, but drinking at someones house with just a bunch of guys around, every weekend untill early morning hours, just has no appeal to me. It's not like these guys are bums either, they all have college degrees and good jobs. They just never grew out of getting totally hammered every weekend.
