A kiss is just a kiss?
Kissing activates a very large part of the brain associated with sensory information because we’re at work making sense of the experience in order to decide what to do next. Kisses work their magic by setting off a whirlwind of neurotransmitters and hormones through our bodies that influence how we think and feel.
If there’s real “chemistry” between two people, a kiss can set the stage for a new romance. A passionate kiss puts two people in very close proximity — nose to nose. We learn about each other by engaging our sense of smell, our taste buds and sense of touch. And through that information, all sorts of signals are being sent to our brain informing us about the other person. In fact, the scent of a man can provide subconscious clues about his DNA to his partner.
Evolutionary psychologists at the State University of New York at Albany found that 59% of men and 66% of women say they have ended a budding relationship because a kiss didn’t go well. It’s nature’s ultimate litmus test, nudging us to be most attracted to the people who may be the best genetic partners.
Research by Swiss biologist Claus Wedekind found that women are most attracted to the scents of men who carry a different genetic code for their immune system in a region of DNA known as the major histocompatibility complex, or MHC.
Scientists suspect that when a couple carry distinctly different genetics for fighting disease, their children are likely to benefit by having a strong immune system. We may not exactly be thinking about parenthood when we connect with someone at the lips, but kissing provides clues to help us decide whether to take a relationship further.
Maybe the elevated divorce rate associated with those who self identify with fundamentalist branches of Christendom could be instantly cured by a little making-out???
