Scientists Find Tears Are the Anti-Viagra
An anonymous reader writes "The male test subjects didn't know what they were smelling, they were just given little vials of clear liquid and told to sniff. But when those vials contained a woman's tears (collected while she watched a sad movie), the men rated pictures of women's faces as less sexually attractive, and their saliva contained less testosterone. Is this proof that humans make and respond to pheromones? The researcher behind the study doesn't use that controversial word, but he says his findings do prove that tears contain meaningful chemical messages."
An interesting test would be to do a similar study on violent rapists.
(excluding those in pre-existing relationships with the victim).
Are they less affected, or even aroused, by the same signals?
If something is there concentrate or synthesize it and test it one by one.
