on average, i spend 9+ hours at the computer at work, then another 6+ hours at home. on the weekends i more or less have to force myself to get away from it and do those little errands and whatnot that independent life forces on you. this has been going on since i was 15, but back then i had to attend school so my computer time was cut in half...
oddly enough this hasn't affected my social life at all. i never had one :)
