I keep fairly active because I like being healthy, but I don't particularly enjoy exercising. If sitting on my couch with a book and a cheesecake were good for me, I'd never set foot in a gym again.
I'm a huge nerd and proud of it. I have an absurdly strange sense of humour, I think math equations are sexy, I read science books for fun, and I'm slightly obsessed with the computer game Starcraft. Usually I prefer board games over video though.
