CHICAGO – "Chemistry look what you've done to me," Donna Summer crooned in Science of Love, and so, it seems, she was right. Just in time for Valentine's Day, a panel of scientists examined the mystery of what happens when hearts throb and lips lock. Kissing, it turns out, unleashes chemicals that ease stress hormones in both sexes and encourage bonding in men, though not so much in women.
Chemicals in the saliva may be a way to assess a mate, Wendy Hill, dean of the faculty and a professor of neuroscience at Lafayette College, told a meeting of the American Association for the Advancement of Science on Friday.
Fisher noted that more than 90 percent of human societies practice kissing, which she believes has three components — the sex drive, romantic love and attachment.
