Fear, Physiologically, is linked to activity in the amygdala of the limbic system. Literary fear is a response to the impeding danger. But for most of us its an emotion. Fear of lose, hurt, insult, separation, rejection, death, pain and sometimes due to abstract notions. With something so deeply rooted in our daily life, irony occurs when we try to run away with the fact that there is fear inside. Putting aside fear for now, let us imagine driving in a car with no brakes, the result is obvious, now imagine someone who is not afraid of getting hurt, would he be rather careful while driving?. Fear is nothing but a necessary emotion purposefully evolved during the course to act as a brake for the living organisms. We speak of safety to ensure that we don't get hurt, we drive carefully on account of being afraid of getting hit. People who are brave have evolved in due course of time to act in a certain manner or environment, and this is called preparedness. Speaking of a stunts man, we know that he can handle what may seem as life threatening to a majority of us, reason his acquaintance with the act. All of us, have some level of preparedness, our ancestors would have faced different fear, for what may seem as an obvious situation, at time it would have been classified as a peril. Does that mean that after a long time will there be no fear at all? I believe no, we can come over the fear due to physical insecurity, we may also be able to cheat death, but will we be able to come with something make us an emotionally invincible?.
So my dear friend if you feel that you are afraid, you are just as normal as anyone else, and all you need to do is to realize that accepting your fear is the only way to overcome it, if you intend to do so. Besides, wouldn't accepting your lack in bravery would be an act of bravery itself?
