I Have my gaming system on 24/7 anyway so i started folding with it, because why just have it sitting there doing nothing. Then when i built a new rig, i had an old one just sitting there, so i thought, hey, why not put it to folding. I find it fun to see your points build up, it makes you feel like your computers are actually accomplishing something. I mean, every folder is a bit enticed to the competition aspect, and if they tell you that they are not then they are lying. So to mean i get satisfaction out of folding, i put unused hardware cycles to use, and i also get the fun added side bonus of the competition for more points.
