     Crying does not seem strange to us. We do it often enough ourselves and  someone else doing it  every day. According to one  of more than 300 men and women in the 1980s, women cry five times a month or so and men about  every four weeks. And the first thing a baby does when it enters the world is to cry  to let everyone know it has arrived. It is not the crying itself that makes our crying   ; it is the  that go along with it. Animals may cry too, but none has tears of emotion. The job of their tears is to bathe and  the eyes. But in our case, at some point long ago, our ancestors developed a  connection between the body organ that  tears and the parts of the brain that feel, sense and express deep emotion.
