Introduction

Stress is a subjective, perceptive experience. When an individual perceives something as being dangerous, the eyes and the ears send information to part of the brain called the amygdala. So in essence, what the amygdala does is sends the distress signal. The hypothalamus activates the sympathetic nervous system. It sympathizes with the body's perceived state of fright and fear and stress. And so the individual has the necessary and requisite energy to either decide to fight or flee the perceived stress-provoking situation.
