yeesh how many times have we been through this one. Relative to wether Dim-mak or Chi mai as a pressure point system can cause death really hasn’t been proven fact of the matter is you just don’t poke and then exepect something to happen it takes a lot of force to really cause injury. Lets put it simplified form if you can shatter a cinder block ( which generally takes 500 pds per square inch). and you apply that same kind of force to someones body odds are your going to cause some kind of internal damage to the organs. But it takes more then just a simple finger poke and retreat.
