What is fear...???

Is fear really a common problem?Yes,absolutely correct. Almost everyone has it ,but its level varies from person to person.If anyone asks me about it my answer will be very simple and clear.
        To me ,fear is a deep rooted thought,just a thought or a group of words which occupies the maximum volume of mind that means it does not allow any healthy thought to  come in.It captures the whole mind and stops the process of logical thinking.
In case of fear unreal images get created in the mind and keep on running all the time that result in secretion of different hormones cause increase in heartbeat, blood pressure and also speed up the breathing rate.It totally lacks reality. We can call it as a state of mind.
It is a habit or nature of an individual that gradually gets developed and we believe it as a sudden effect.
The reason of fear are many but the most important one is common belief .we don't want to know the fact of any happening. We just believe other words without investigating the fact and we also frame a pseudo result on the basis of others belief .
The only remedy to stay away from this problem is to remain positive always and to be confident in every decision.
