Hitting yourself in the head for 'punch resistance'

It probably would help, but at the cost oc brain cells. I remember reading somewhere that marciano and his brothers would line up across the room from each other. they would then sprint head first at each other and collide head to head winner being the one standing. it probably killed a lot of brain cells, but no one ever argues about marciano having a weak chin. he was definitely born with a very strong chin, but i bet the slamming of the heads for years has at least a small increase in your ability to take a punch

 

How much do you want to bet?

 

Couldnt help my self reading the topic and not looking it up HAHAHA

Really wanted to know, how can you come up with these type of questions...

 

I'm inclined to respond properly, but I think I'll just leave it as a joke.
Now, how do you stop your hand from being broken? By punching your own hand
