Economy. It's more of a love-hate relationship though. I studied economy for a few years, but around here you have to be pretty good at math to get a decent degree. I suck at math. But I enjoy reading some theory, provided there isn't too much calculus or some pesky integrals in it.

Oh, and it fascinates because you can learn so much about behaviour and because you can stuff practically anything into an economic model. It's interesting to scale down the world and even out all the bumps. I'd probably really, really love mathematics if I was any good at it.
