My two cents; 95% of unarmed street fights go to the ground fast. I've been able to anticipate and avoid most violent confrontations for just over 45 years. So what happened back then? A drunk Brit at 2:30am hitting his girlfriend in my campsite in Yosemite. He had 40 pounds on me and lots of fighting experience, but he was quite intoxicated. In two seconds we were on the ground and two more I had his head in a scissorlock. I locked my ankles and tightened down with all my strength. He started gasping and the girlfriend started pleading with me to let him go, but after ten seconds he went limp. I saw him nursing a bleeding nose the next morning. Know your illegal wrestling holds!
