Fear can not only paralyse a human being, it can also drive him to do things he would not do in normal situations.

Exactly, fears are so terrible, bad to experience. Everyone experience fears too. I could remember when I was still at collage, we normally go to the school farm to gets some fruit and satisfy our taste, so it happened that my friends had already planned on how to trick me, so they got a toy snake and as soon as I jumped down from the tree they threw it close to me, all shouting snake! Snake!! and was on the run. I couldn't remember how I scale through a fence without the help or support of anyone or thing, which I normally seek for support when jumping.
