"Central to any discussion of the response to a perceived threat is to understand the physiological responses that the body has when a potential menace is initially recognised. One of the first things to realise is that your thinking stimulates the physiological reaction, and that it is your own thinking which can therefore control and harness this response. 'Fear is in the mind of the beholder.' Fear is experienced as a sudden release of adrenaline (a combination of two chemicals, Epinephrine and Norepinephrine), followed immediately by the associated physiological responses. If left uncontrolled, these responses can have a devastating effect on both the body and the mind."
