One of the biggest obstacles to becoming a master presenter is those butterflies that seem to be fluttering around in your stomach before you start to speak. Although you are an expert in your subject, your fears create a fight/flight reaction. Your hands become cold, your vital organs stop functioning properly, and a majority of your brain’s blood flow shifts to the ancient reactive defensive areas that reside just above your brain stem. Your mind and body begin shutting down. You are not your best. However, you can speak to small and large audiences in total comfort and excitement if you only understand what is really going on.

In the 1990’s a group of Italian neuroscientists discovered what they call mirror neurons. These brain cells, which are scattered throughout your brain, react when you observe the behaviors of others. This also happens when you sense the intentions...

If you occasionally have problems such as shortness of breath, wheezing, a frequent cough, or chest tightness, chances are you are suffering from asthma. And, there's over a 50% chance that your asthma is being caused by an allergy.

When allowed to run amok, this part of the brain will cause high levels of misery. The second part of the brain that is involved with fear helps us to react to any threats to our safety. Unfortunately, in many instances our ability to anticipate may cause us to falsely fear something that is not a threat. Some people unjustifiably react to perceptions that do not represent a threatening situation.
