So it's the trauma that does it? Where's the biochemical basis of trauma? I mean, when you get hit by a car and you get shock from blood loss, you die of shock from blood loss but you also die from the car. You could solve the problem with better EMT's and blood transfusions and stuff but you could also solve the problem by having better public transit and not having cars everywhere, you know?
