Way back in time the world was very dangerous. One did not venture far. Imagine stepping out in the open and a tiger decides to come after you. Your heart beats fast, a slight sweat breaks out, breathing increases and you take off running for safety. That is a normal response to danger. But, those living in a constant state of stress have similar responses. It is like they are running from something that is not there or that is not going to happen. Worry, hyper vigilance, suspicion, and general anxiety are constant friends. You see, your body does not know the difference from a real danger and a perceived danger, so it responds the same. Be aware of what your head I telling your body to do.
