Sixteen, apparently. Seventeen if I'm willing to do it without objecting to the morality of fighting with kids.
Which is kind of scary, considering that I'm supposed to be a pacifist.
I imagine it was being able to kick more than 3 feet in the air. I always knew having that extra foot would come in handy.
edit: actually, the score being as high as it is can probably be attributed to the fact that I had to admit I've bitten people in fights. A
long time ago, true, but still, history could easily repeat itself.
