tempehmomma,
Did you catch Fight Science on the National Geographic Channel? The show had a bunch of scientist using the very latest in technology to prove what was myth and reality as far as strikes and kicks as well as weapons. It was very informative. For example, for a hand strike, the only fighting style that generated 1000+ lbs of pressure was the common boxing right jab. The other martial artists using their own particular style couldn't generate that much force. Who would've thought.
Another one was the front knee kick as used in Muay Thai. It was rated as super deadly to the human body. When they release this on DVD it's worth owning in my opinion. They'll probably repeat this so check their website for times.
