I am browsing thru several pages of a magazine when I come across a brand name "No Fear." But this is not to promote their products or whatsoever. :) I get focused on the word FEAR and thought how and why we feel afraid sometimes. Is this feeling a prerequisite of something? Is this feeling created for something we people need to realize? These are few questions I will try to answer.
Rapid heartbeats, too much sweating...
On my opinion, fear lives on the concept of not knowing something AND also when we know too much of a thing. We often feel fear when we less know a thing that we need to do or worse not even knowing at all. Having no idea of what will happen next creates fear.
Think about death. Most of us fear death and I am one of it. The simple reason why is because I do not know what will happen to me after life. Who knows? To mitigate this fear, society created beliefs and norms which will help people learn what is death. In turn, accept death as a form and part of man's life cycle. Some believe in reincarnation, some believe in fruitful life after death, some believe that we will either go to hell or heaven depending on how He will weigh the life that you have on earth, and such. But despite this, man still fear death.
