Dear 100 Hour Board,
Why do some people jump at loud noises when others don't? I can be sitting around, not the least tense, but upon hearing an unexpected bang I might jump a foot in the air, while the person next to me might just sit there and feel suprised. What determines the occurence of this involuntary twitch?
The less relaxed you are, the more you will respond when surprised. Of course, there are advantages to being easily surprised--you can react more quickly to actual emergencies. Certain past traumas, or just the way you were raised, can also make you more jumpy. If this is a serious problem, or if you have other symptoms of serious edginess or tenseness you can learn more at: http://www.wrongdiagnosis.com/sym/startling.htm
