But if people train to fight, they should rely on the fact that you can not block or parry every attack. Sometimes you have to take punishment. I for one will always guard my head. I think for my body that I would rather take any punishment to the body. We learn to control our kicks and punches, but for the reason that if you miss, you do not want to expose your back to your opponent. When it comes to fighting or even training with arm guards, it is all out. I think that one thing that is missing in karate now is the mental prepareness that I can take or block anything that you throw at me. As for the guy who had surgery on his nose, he will be the first one that will say it happened because he did not train enough for the tournament. When you lose a match you should be looking for the reason why, not a law suite. Just my thoughts, but I could be wrong.
