This National Geographic video confirms the legend of the one punch knockout and shows the anatomy of what happens to the body when you are punched that hard.
I'm so, so wary about trusting these guys because of the other parts of this series. It would be nice to see some better studies being done on the actual effect on the brain after impact, rather than just crash dummies.
Hey, the energy traveling through the punch from the ground up????-why chi in Kung Fu...is so important to develop....
