Researchers did another study where they strapped a bunch of guage pads to 'armpits' to collect their sweat while they watched horror movies. Then thet taped the fear-sweat-soaked gauze under the noses of a second set of participants. Those subjects were then shown pictures of faces with completely blank expressions, and scientists found that people exposed to the ''fear'' sweat were more likely to guess that the expressioless faces were fearful.
''Our findings provide direct behavioral evidence that human sweat contains meanings.''This research was published in the Journal Psychological Science and was funded by the National Institutes for Health. : http://www.rice.edu/
