"Or a Newsweek article that described recent experiments conducted to map the brain differences in men and women. The study showed that when both sexes were presented with photographs of facial expressions and asked to determine what emotion was being expressed, women were able to correctly identify a sad face ninety percent of the time on men and women. Men, of course, had more trouble with this. While they could correctly identify sadness on men's faces ninety percent of the time (big surprise), they had a seventy-percent success rate when it came to identifying sadness on women's faces. In addition, PET scans revealed that men used significantly more of their brains during this exercise than women did, and they still got fewer answers right."
