It just all depends on people's lifestyles. This is my weekly routine:

Monday - Work, go home, play game.
Tuesday - Work, bowl in a league, go shopping, don't really get to play.
Wednesday - Work, go over to a buddy's and hang out and drink for a while, maybe get a couple hours to play.
Thursday - Work, go home, play game.
Friday - Work, this day varies some, but usually I just go home and play game.
Saturday and Sunday - These days are tossups. One of the two mornings I go and practice bowl with my friend so I'll get home after that and some lunch around mid-afternoon. Depending on other plans, I'll hang out with some other people later on or just stay home and play my game. Sundays I sometimes go to a local sporting event and am gone most of the day so might only get a few hours to play that night.

So that's my life in a nutshell. Some people are more socially active than me, some less. I think I kinda fall in the middle somewhere. I play maybe 4 hours a night at most after work when I'm not doing something else, and if it's a weekend day I can sit there and play all day. I started over with a new char and I have 6 50s - 4 battle classes (5 if you count smn/sch separate), 1 crafter and 1 gatherer.
