100% nerd (lots of my free time is spent playing board/card games with friends) while staying as active as possible. If asked where I would rather be right now, the answer is usually on an ultimate frisbee field. I love competition, but only for the thrill of it, I don't really care who wins.
I also love over-analyzing things (I have a particular affinity for efficiency and optimization) and logic. You could tell me the sky is green and I won't disagree, I'll just ask for proof. I frequently like to play devil's advocate just to get some food for thought. Recreational banter is good for the soul.
