Listen, our goal, my goal, is to prevent injury and promote health. I'm an emergency physician. Injury prevention and promoting health are the two main things that I'm interested in. As an emergency physician, I know that when people get struck in the head it can lead to concussion and also severe head injury.
There are studies being started as to the rate and severity of injuries. We already know that there have been people killed from mixed martial arts, from blows to the head. I don't know the actual rate, and I don't think it is known into the future what the long-term sequelae are, but we know there are serious potential problems. So yes, it's our role to continue to advocate against this.
