Traditonal Chinese Medicine takes advantage of the flow of energy through a system not clearly identified in Western medicine, but which is readily exploited for healing or for destruction. This system consists of meridians that conduct energy through the body and are accessible at specific points called pressure points. These points exist where a nerve comes to an end, crosses another or forks. The array of the most significant points for disabling the body exist on the fore arms,. shins,. and the head particularly those along the jaw line to the back of the neck. IMHO, beings know this instinctively which is shown in the adaptation of armor to block access to the most dangerous of points. As shown, the neck piece and jaw protection block ready access to the hot spots.
