Why do women cry more often than men?

No it’s not because women are emotionally weaker than men, as sexists among us often suggest. Women are four times more likely to cry than men. And the reason is primarily biological. Research shows that men’s and women’s tear glands are hormonally different. Until age 12, boys and girls have equal levels of the hormone prolactin, which explains why youngers of both sexes tend to cry with the same frequency. However by the time a woman reaches age 16, she has 60 percent more prolactin than her male counterpart, and is more apt to cry.
