Why do we fear so many things ?

 Name it ,tsunami,virus outbreaks, N.Korea's rocket, American mass murders in schools, pranksters

from Australia. ect. 

  We live infear,are we not. Everyday there appears new forms of fears to scare the joy out of our lives.

I think the main reasons that allow fears to dominate our psych are : the soft living that affluence 

serves us, the over protecting state welfares , the artificial surroundings created by the ever 

imaginative consumerism providers, the hedonistic inclination of our own and so on.

  Perhaps if we take more hardship from time to time, thinking of death and horrible injuries as  normal

events for all living things,man,plants animals ,even rocks, we may be less fearful of the any threats

big or small.
