re: Are kids who take Karate more or less likely to get into a fight?

I boxed when I was young. A couple tapes got out of me and my friends beating the crap out of each other on off days from the gym. Trainer didn't really like us sparring too much at the gym. That made it less likely anybody would try to mess with you at school. It wasn't about how good you fought, it was about balls. I only got in a few fights. Several occasions I was a "ref" of street fights. No jumping in, stop when I say it's over. A few times people didn't obey the two rules and I got to tangle a bit. It is quite fun to use your skills, but if your kid knows the consequences and your a strong parent he will keep it in check.
I also found my number one advantage over others was condition. I think most fights went to the ground because people get exhausted after a minute. I could go five no problem. Counter for one minute, turn it on.
