CPTLEO1 derrrrrrrrrrrrr!!!!!!! I completely and total grasp the concept that lack of oxygen to the brain causes death. What I was refering to is how lack of oxygen can happen. All the processes that I explained have the end result of hypoxia. So no that is not crap, further study would show that these injuries are how deer and people die. Addressing the strangling issue you areblocking theblood flow to the coraded artery which is nothing like what we do to deer.
