I've seen a person who break "batang pisang" with just a punch.. And its the real "batang pisang" of course.. Try la tumbuk batang pisang with your bare knuckles.. you'll know if your punch is strong enuff.. These true martial artists can be really scary sometime.. They seem to have some kind of "internal energy" which is invisible to us..

But I also seen in front of my eyes, a Taekwondo instructor with black belt got beaten badly by a bunch of teenagers.. I actually know that guy.. Yes, it wasn't a fair fight, but it reminds me that no matter how strong you are, if you are against a number of people, you better back off.. That Taekwondo instructor was rude that time, dia ingat dia kuat, that's why he kena belasah..
