There are checks and balances in science. There's somebody checking the people doing the science, and then there's somebody who checks the checkers and somebody who checks the checker's checkers.

For me, boxing's like checkers, and MMA's like chess - there are so many ways to win the match. It's not barbaric; it's boxing, kickboxing, Jiu-Jitsu, wrestling, cardio and it's all reached such an amazing level. As fans learn more about the sport, they just fall in love with it.

My computer beat me at checkers but I sure beat it at kickboxing.
