We all have cried at some point of time or other. Scientists are still speculating the reasons of human tears. Pain can make even the animals cry but only humans cry due to emotional stress. There are many contradictory theories regarding crying. The pang where our heart is followed by tears swelling up in our eyes is a common experience and we all had our share of it. Even good books, movies and music can induce tears. One of the opinions about tears is that it is the result of the human capacity for empathy. Often we merge ourselves with the characters of the books or the tragic hero of a movie.
