Out of curiosity, how have you managed to "wreck" three computers in six months?
Anyway, I read. Whilst everything I've read lately has been for my studies, before I started university I used to consume a novel every week or so. I don't watch television either, but I do own one for watching movies or playing computer games (I use my computer as a gaming machine rather than dusting off my games consoles, though). I write. I build models out of Lego. I walk - living in a rural area helps, because after fifteen or so minutes out of my house I hit wide open countryside. Mostly though, I try to socialise; between having a full-time job and being a full-time student, my free time is limited, so I try to see (or at least speak to) other people as much as I can in order to keep hold of some remnant of my sanity.
