Assuming I'm up 16 hours per day on average (Wake up at 11-12ish, go to bed between 4 and 4:30am), I'd say about 15 is spent on the computer :x Since I do virtual school, I have to be on here for it, and then I just sorta stay... XD; Really, I'll admit I'm far too addicted. The first thing I do in the morning is lean over and open my laptop, and check up on stuff. And then I'm using one of my computers right until I go to bed. Lately I've been having to make dinner for everyone around here , so that's why I deducted an hour from the 16. So yeah, I'm on the computer literally all day, every day, unless I have to go and do something else.
tl;dr More time then I do off the computer.
