“Fear” is a very common and ancient emotion and there’s no human on the face of this globe that doesn’t experience this emotion. We fear due to the awareness and realization of something bad about to happen; the apprehension of a negative event, which might harm the person. Fear is Anglo Saxon in nature, and it originally meant a calamity or disaster. Later on as time passed fear came to be recognized as the emotion that accompanied any catastrophic or disastrous event. Today almost all negative emotions are tagged with fear and can be used to define fear; such as nervousness, dread, terror, anxiety, uneasiness, and panic. In short fear is a state of arousal or provocation that a person experiences in reaction to a clear and present danger.

Fear activates a mechanism called the fight-or-flight mechanism; the body is prepared to deal with any kind of physical threat or harm by the release of a rush of adrenaline. Dangers such as a person approaching to hit a person, actions like these need a response which has to be very prompt, even a second’s delay may result negatively resulting in harm, hence the person in that quick second makes the vital decision.
