Differentiation, Validation, and Fascination.

I'll answer your question even though it wasn't meant for me (LOL). I don't like cars or sports, but I also don't like shopping or dressing up, I do enjoy home repairs (though I suck at it) and I was very good at math and science and nothing pleased me more than to set the curve on a test and screw up the GPAs of the Young Republican jerks who attended my high school.
