The human brain realizes it must fight or flee. It sends messages to the Central nervous system tell it what the body needs to do. It will send a message to the endocrine system telling to release endorphins, a natural chemical, that will then be passed around the body to carry out the proper function. If a man must save a child from a burning building the endorphins will enable him to move heavy objects and grab the child and run fast to safety. If a woman sees a bear her CNS will signal the endocrine hormones to release the endorphins she needs to run fast and get away from the bear or to move with extreme care to get away from the bear. If it releases more endorphins than are used the person will have a racing heartbeat or shaking body.
