• The following list is a list of the human body's weakest points. The following list (and pictures) were obtained from Black Belt Tae Kwon Do by Yeon Hwan Park and Jon Gerrard.
• These diagrams detail vital points of the human body. I chose to use a tae kwon do guide instead of the traditional nerve/vein guide since throwing cards lack the penetrating ability of spike / star shurikens.
