From the ancient days of mankind. The man has a tendency of fear. This fear is embedded into his personality and keeps passing on generations. So why do we fear? Well to answer that question we need to discuss various kinds of fears. Presently, some deals with the fear of darkness, fear of heights, fear of water and fear of spiders. Well, Spiders are quite spooky in my opinion. Everyone has got some kind of fear in their life. On a ground level, we can say that fear keeps us away from dangers. So, you are scared of riding a horse then your body may know that it cannot do it. But how can our body decide it even before experiencing it?
So fear is a heredity? The answer totally depends on the perspective of people. We grow fear based on our environment. For example, the kid from a slum is never scared to hop on a crowded bus. While a kid from a rich family will tremble doing the same thing. It all about how we shape ourselves in life. If our ancestors had feared, then there would no discovery of fire. We would be still living in the stone ages and hunting animals.
