The late Kickboxing champ Joe Lewis claimed that some people have glass jaws but strong bodies for blows, and some have strong jaws, rarely get's knocked out to the face, but have weak bodies. I have a weak central body. Blows to the shoulders and my face don't phase me. Based on my experience that is. My face feels like stone. It annoys me but I rarely get phased by blows to the head. Never neen unconscious. But even holding mitts, full force, continous body shots can take my breath away. So which is preferable in a fight, if you had to choose?
