I know it really is disturbing and it seems to be happening more now a days. My daughter is a brown belt in Karate but our motivation wasn't so she could get into fights in real life - but just to defend herself. We have done many tournaments and she has done sparring but I know this isn't what you're talking about. But I've recently thought about taking her out the sparring training because I'm concerned about jolts to the head, causing 'accummulative' brain damage. They know that football players and of course boxers get early onset dementia because of blows to the head. Even though my daughter wears a padded helmut I'm still concerned with shaken brain. Sorry for going off topic but this has been on my mind - how I'm going to explain this to her hard headed instructor. Thanks NF for posting this problem.
