 O'Shannock is among the authors of an open letter released by the Brain Injury Association of America calling for power slap to be banned. The blows sustained in a slap fight, they say, are worse than what you might experience in football or boxing, largely because competitors are not allowed to defend themselves, meaning they're likely to be struck on the head multiple times in the same place over the course of one fight. Right, yeah, you've got to just kind of hang in there and you close your eyes and wince as they whack you.
