for the unintiated, here's an example:
Here is MMA legend Dan "Hendo" Henderson in the white trunks knocking out some random chunky scrub from Russia. I can't even remember the guy's name, maybe someone can help me out. Anyway, notice how after Hendo knocks the dude's block off and his fat, out of shape carcass slams to the mat, the ref immediately steps in to stop it. If this were boxing, he would have been given a standing 8 count to gather himself and proceed to potentially suffer more damage and blows to his already sensitive brain. If it were football, he could have lied to his coach about his symptoms and be allowed back in the game to, again, cause more damage to his tender brain. MMA saved this Russian can's life so that he could be healthy enough to grace future shitty cards with his presence.
