That's possibly true. I've never had to do it. I've also never had to shoot someone. Probably because I've never been in a bad enough situation. But there is no doubt in my mind that I would do anything I had to do to get out of a bad situation.I would never support biting for self defense, for a simple reason. I don't believe that most people are able to willingly bite through another person's skin, even in self defense, and think they would be more willing to choke or punch the other person.
