The Misconception: Kissing is only an expression of love.
The Truth: Kissing transmits germs from the male to the female to bolster the female immune system before and during pregnancy.
Take a step back and pretend you’re watching animals in a zoo. Let’s go with groundhogs.
You see one groundhog walk over to another one and stick its tongue in the other’s mouth. They flop their tongues around for a minute and then go about their groundhog business.
Kissing, let’s face it, is sort of strange. Why so much passion? Why such overwhelming emotion?
Our mating behaviors are such an integral part of our behavior, we rarely consider why we think and feel the way we do. We know hamburgers are delicious, but why? We know we find breasts and biceps attractive, but why?
We love to kiss, and we do it instinctively. The urge to do it springs up from deep within – but why?
One of the answers is the cytomegalovirus.
It has been a hypothesis for a while, but recent research by Colin Hendrie from the University of Leeds may have pinned it down:
“Female inoculation with a specific male’s cytomegalovirus is most efficiently achieved through mouth-to-mouth contact and saliva exchange, particularly where the flow of saliva is from the male to the typically shorter female.”
Sperm just don’t cut it when it comes to transmitting immunity.
According to the research, kissing transmits germs from man to woman, and after about six months of it she becomes immune to the bad stuff in the man’s body. By the time the baby is born, it is immune to the things the parents are immune to.
The behavior is so deeply evolved in our brains that homosexual men and women still kiss, and they get all the latent benefits – connection, love, ribald desire, immunity from the partner’s germs.
You kiss babies and pets, sacred objects, the ground.
When it comes to kissing, you are not so smart, but you are healthy.
