• When a living creature is exposed to some type of life threatening stimulus, it immediately responds to protect itself.
• The stimulus is evaluated on its basis to harm the organism, and the organism then decides it must either fight off the threat or flee from it.
• If the organism senses that the threat is too menacing, it will opt for escape and evasion instead of confrontation or counterattack.
• If it views the threat as insignificant for harm it may even go on the aggressive and attempt to repel or counterattack.
• As a part of the survival related protection system afforded to more physiologically advance living creatures, a human’s Autonomic Nervous System is responsible for maintenance of the body’s equilibrium and functioning.
• It has the task of making the body physically stronger, or "in sympathy" with a perceived threat to one’s well being.
• The ANS is responsible for regulating body functions like temperature, breathing, circulation of blood, and a host of complex chemical balances.
• When the sympathetic portion of the ANS activates, a living creature is prepared for fight or flight.
• Our fight or flight mechanisms are if full function when the predominate emotion we feel is fear. We respond involuntarily in our best interest of self-preservation.
• An untruthful person views an information gathering or probing interview as an exercise in survival.
