>>A "loaded" fist is a really good way to break your hand.
That it true, my father was a doctor for 50 years and he treated a lot more people for broken hands, rather than a broken face. The bones in the nose can be broken, but other than than, there is not much chance of being able to break a bone in the face with your fist. That is why people who really know how to fight hit with the side of the hand, where they have strengthened the bone by breaking boards. I use to change tires and I would beat the hub cap on with the side of my hand, and in time the bone seemed to get harder.
The reason boxers wear boxing gloves is to protect the hand. Because the bones in the fist are so very easy to break. Thanks, JohnR7
