Ever hear of the term “Glass Jaw” or “Glass Chin”? These describe those who can’t really take a punch, and to be truthful, most people who don’t fight have pretty weak chins. Because the jaw and chin area is so large, it is an easy spot to KO someone- and it doesn’t take a lot of power. A swift punch to this area can easily result in the brain temporarily shutting things down (KO) allowing you to GTFO of the danger you’re in.
