"It's hard to think when someone's trying to kill you. We human beings aren't wired to be rational and creative when we know our lives are in danger of a swift and violent end. The body has definite ideas of which survival strategies it prefers to embrace, and those are generally limited to "rip threat to pieces" or "run like hell." No thinking need be involved, as far as our instincts are concerned. Our instincts were a long time in the making, though, and the threats that can come after us now have outpaced them. You can't outrun a bullet, and you don't go hand-to-hand with a gunman unless you're certain you are about to die anyway. Speed and mindless aggression weren't going to keep me alive."
