I'm on the bad section too, at work I sit in front of the box for about 7 hours, but try to break it up a little, with lunch and walkies breaks. Then I get home and is another 3-4 hours (sometimes 5-6) as you can see a very active lifestyle. I did see once a copy of Doom that was plugged in to an exercise bike, so you had to pedal to walk forward. If someone could find a way of accelerating render time using pedal power, I reckon most of us would be very fit by now.
