 Second, when you decide to fight, hold nothing back. Use every weapon available to you. The fight is already not fair, so you do what you have to do. You bite, you kick, you scratch, you scream like a wild animal. It's not the age of the fighter, it's the attitude that counts. And third, the older man didn't give up. He was knocked to the ground and then kicked in the head. I think many older people would have given up at this point and begged for mercy, but not this man. He had the heart of a warrior, so he was able to fight back and prevail.
