It's hard to understand if you're not affected by it. You've heard the term "Stage Fright"? This is the same. Something about being put in a "performance" situation triggers the fight or flight reflex. At first, you're a deer in the headlights. Then, your body floods with adrenaline. The whole thing makes higher level thinking extremely difficult. I don't agree with the parent poster that it's "damaging to people's health", though. It's just something that happens. You recover pretty fast afterwards.
