Lots of little things. My chores for the last 8 months or so have included cutting up the wood pile behind our house to fit in the yard debris bin. I'm a half-decent artist. I have eight pets, and was the primary care-taker for them for a few years. I have a book called "How to Stay Alive in the Woods" which is a general survival book, and will serve me well. I went to school and had health and safety classes, which included basic first aid. I've also gone fishing with my grandfather several times. My summer project last year was making a shield, sword, and spear. Would have made armor too but it would have been too expensive. I've been in a sculpture class. I've taken an interest in siege weapons, and done research on them. I've taken a very basic chemistry class. I know how to swim... I've taken an accounting class, and several architecture ones. I have a composite bow, and have used it, but I'm a poor shot. Speaking of which, I was decent with that rifle, so I should add Adequate Crossbow-user. My dad was one of the top wrestlers at his high school, and we still wrestle at times. I was in pole vault, and so I know the basics of moving a long pole around and have some of the musculature suited to it. I've always been very interested in strategy games, military theory, and tactics in general, and have done research.
My dad is also a biology researcher at John Hopkins and when I visit him we talk about anything and everything about technology and science. So that adds some.
EDIT: I feel I'm just very 'Jack of all Trades, master of Records', more than anything else.
