Everybody knows that Bruce Lee has never been defeated before in
his life and that he is a great martial art expert.
But why is it that he has never been defeated before?
Is it because he trains regularly and so is fitter and have
bigger muscles than his opponents and so could defeat them? Is it
because his speed is faster than his opponent?
I'd say it was because of his quickness. In point sparring
thrashing your opponent isn't necessary you only need to make clean
contact.
