Rogan proposes authorizing blows to the back of the head

"I'm not sure if hitting the back of the head should be banned - it doesn't make sense to me and it should be allowed. If you discuss the matter with a neuroscientist, he'd say it's a particularly vulnerable area. But isn't it the temples? Isn't it the eyes? It's just as vulnerable," Bloody Elbow portal quotes Rogan as saying.
