Ad Vingerhoets is probably the only “crying professor” (from the University of Tilburg). Why do people cry? He says that crying is not so much about feeling sad, but about feeling hopeless and powerless or other feelings like altruism, self sacrifice etc. He says women and children mostly cry with someone else while men prefer to cry alone. In Northern, colder countries, people cry more because in warmer countries there are more social conventions. The less testosterone, the more easily men cry. Source: Article, Image: flickr.com
