Yesterday on the East Coast on either the National Geographic Channel or Discovery Channel they showed a special documentary called "Fight Science". Basically they took masters from a couple different martial arts, and put the different styles to the test to see which one was the most deadly. As it turned out, boxing delivered the most powerful punch at 1200lbs of force, equivalent to a person in a 35 mph car crash into a brick wall without a seat belt on. The fastest strike was given to the Chinese Kung Fu style, where the dude struck the target 3 times faster than the average speed of a snake bite. The most deadly strike, however, didn't go to any of the martial arts you see these days, but to one very old and very rare type, Ninjitsu, Ninja style martial arts. The dude spent 25 years perfecting one move, the hammer fist, and when he struck the target (the chest of a crash test dummy that had electrodes in it to detect the power of the strike), it didn't seem like he delivered much force or anything; he was also very slim and lanky. The force and precision of his strike, howevr, was so deadly that if he performed it on the average human being, the force of the strike would push the chest 2 inches backwards into the body, sending frantic nerve signals from the brain to the rest of the body to immediately stop the heart from beating. Thus, the opponent dies on impact. Pretty crazy, huh?
