CHOICE B A question that always comes to my head when conversing on the issue of Natural selection is the fear of heights. Is fear something you learn overtime or is it something you inherit. It is said you fear what you don’t know, so is fear nothing more than when your brain cant rationalize an experience at that particular moment. This irrational fear is identified by the name of Acrophobia. A further notion that has crossed my thoughts is why is it that us humans have a solicitous sensation. There is no human emotion that is potentially as devastating and disabling as anxiety. Unlike genuine fear, anxiety is fear without a known cause. It doesn't mean that the anxious person can't say something about the discomfort, but it is never an adequate explanation for the irrational fear. It is without doubt seen that anxiety is a overwhelming emotion. Unlike fear, anxiety has a disintegrating effect on the body. The intellect keeps searching futilely for a reason that can be addressed, and finally gives up in fatigue. While fear mobilizes the properties of the body, anxiety has the opposite effect; the intellectual resources are scattered. Anxious people find it hard to relax, sleep, or even carry on a discussion. They become petulant and jittery and search frantically for some form of relief from the devastating feelings. They may leave the situation that produced the anxiety only to find that it still persists. If the anxiety is free floating, then events that cause most people only little concern (like driving on a parkway) can cause the anxious person to experience a high level of anxiety, and such a person may avoid them all in all. Free-floating anxiety can attach itself to just about anything that would be only of casual concern to the majority of people. Events like flashes of lightening, a threat of a flash flood, and even the imagined potential of having a life-threatening disease can cause continuous anxiety.
