Let me give you some different advice. Don't try to prepare yourself for brain trauma or spend time learning the ultimate self defense system, start trying to avoid being in situations and around gorilla people in general.
Learn to shoot and handle guns, if it ever really came down to it that's the best kind of violence to be somewhat prepared for (psychologically, and muscle memory wise). On the other hand, almost every situation that involves you getting punched in the face can be avoided.
