Speaking in front of the public or giving presentations to groups or at business meetings is a daunting task for many people and can cause dramatic levels of anxiety. For some people the thought of standing in front of a group of people can be so terrifying that it's avoided at all costs, whereas others may just feel mild levels of nervousness. Symptoms vary, but typically include extreme anxiety prior to, or even at the thought of having to verbally communicate with any group of people.  The fight and flight stress response is triggered, increasing heart rate, blood pressure, oxygen intake, perspiration, stiffening the muscles, tightening the throat, and disturbing the thought processes leading to a greater incidence of “ums” and “ahhs”, forgetfulness and confusion. The anxiety generated, in extreme cases, can lead to a full-blown panic attack.
