Nick,

You know why there are weight classes in boxing, wrestling, and fighting? It's so smaller guys don't get fuckin' killed by bigger guys. Derp.

Leverage works the same for big guys and small guys. It isn't some hidden advantage for a smaller guy. A big guy that knows angles and how to use leverage will beat a smaller opponent that knows the same. You saw the all other things equal part, right?

It looks like you hate money to me. Let's get a bet going on this.
