I used to sleep badly, until I started to follow one rule: no screens after 9pm, whether it's for the TV, internet or games. Now I always get enough sleep, unless I break this rule for some reason. Funnily enough it doesn't seem to matter if I read in bed, which makes me think that the backlighting on screens may have played some role in stuffing up my circadian rhythms.

I only play fitness games that make me sweat: currently New U and My Fitness Coach. If designers came up with a game that could match those intense levels of exercise with a long, involved storyline I'd buy it. So far no-one has. Instead this market is full of simple, cheaply-made, narrative-free games. It's this misguided label of the casual gamer that's leading so many developers astray. I don't care about the time it takes to pick up a game. I just don't want to be sat on my bum for 5 hours at a time, getting fatter.

I find myself printing out less since I got an e-reader, but it's still just for certain documents. Temporary stuff, mostly. If I could doodle and use colour that might cut it down some more. I don't think screen size makes a lot of difference for me, but it might for some people. You can't pass round electronic documents as easily, but what if someone built an e-reader that allowed you to dock with other readers and transfer files between them? That would change things (provided everyone in the office has compatible machines).
