Watching too many Chinese movies about "Kung Phooy" might give the wrong idea about combat "magic".
Here is a story about "combat". I have a friend who is a fourth Dan black belt in Karate. He told me many years ago that Karate is more a way of life than actually fighting, but of course it is very successful in defence! Except for one thing, he has said many times to youngsters learning Martial arts.
"Absolutely nothing is a defence against a perfectly delivered, unexpected, straight Left!"
