dtjohnson writes "Researchers at UC Santa Barbara have found that women have a remarkable ability to assess a man's testosterone levels and his interest in fathering children by looking at his facial features. Sixty-nine percent of the women were able to correctly judge a man's interest in having children merely by looking at cues on photograph's of his facial features. Saliva samples were also taken from each man in the study and tested for testosterone with a $2,000-a-pop test. The women in the study were able to correctly identify the men with the highest testosterone levels just by looking at their photographs. Of course, the study did not look at what men were able to tell about women by looking at photographs of their female body parts."
