I have to ask a question here. I do not mean to offend anyone, but you all keep talking about fights against multiple attackers. I'm 36 and lived a fairly rough life, I have only ever been in one fight against multiple attackers. You all are traing for a circumstance that if it is a real threat in your life, maybe you should change your life style. I recently started training in Hapkido, and feel that in 99% of most situations I was ever in, it would have worked well. If some one knows more than you, it does not matter the art or the style, you are going to be hurting when it's all over.
Again no offense is meant by this.
