During my school years I was more interested in fighting. At twelve I started Tae Kwon Do classes(basically kick boxing), and had a friend who was a wrestler at school and I used to go to the place where they'd work out and grapple with them. I had a heavy bag, a speed bag, and weights in the basement. I was into weapons a lot too, knives, throwing stars(shurikens), nun chucks, and some I made myself - I used to make my own chucks and weight them with lead in the bottom.
I was a real asshole back then. Always challenging people to fights because it's what I worked at. This is probably all blown out of proportion, but that was some of it anyway. I'm a lot different now though e.g. like writing poetry on a Satanic forum.
