Bollocks, this is yet another attempt to start an argument and to troll, you don't actually want to know anything about whether I spar full contact or not because you already know that we do at my club, I've said so numerous times, I even got censured by a poster, Steve, here because he thought my breaking a student's nose was disgusting etc etc. Ask him. I've also said I've been KO'd twice, but you don't actually want to know, you prefer call me a liar and start one of your online arguments merely because it amuses you. Well son, I think you should concentrate on your own training and grow up.
I don't know why you think that my training style has anything to do with others training and why they would check what I do before deciding what they do, they aren't that kind of stupid. The information on what happens to the brain when hit has been available for a long time, you can choose to ignore it but it has nothing to do with what I do, I recommend people look at facts and make their own minds up, surely you can do that without wondering what others do?
