subject: Flight or Fight Response a Dying Reaction [print this page] A couple of years ago a boy was actually killed, a seventeen year old boy. The explanation, the driver was not looking, my explanation: THE BOY SHOULD NOT HAVE JAY WALKED! Sorry he died but he didn't use his head. The argument: Humans don't develop the frontal lobe in their brains until nearly twenty-five. The frontal lobe is the region of your brain that apparently makes you think cars are bigger than you and dangerous. Actually it is responsible for the consequence effect, meaning you understand that there are consequences for your actions. With this in mind I can say one thing, we are programmed to die.
