Again, I would like to turn to the pages of the January/February issue of Discover that hematophage gave me for this week’s post. Next time, you are about to place a big wet one on your loved one or some guy you just met at the bar (we don’t judge here in the Abbot lab), I would like you to think of this:
1. Humans are the only creature that purses their lips outward. In fact, we are the only animal that kisses.
2. Kissing is not universal. The Roman military introduced kissing to many non-kissing cultures. Then, European explorers began to spread the kissing tradition.
3. Claus Wedekind of the University of Lausanne in Switzerland reported that women preferred the smell of men who had a different mix of immunity-coding genes than themselves. This means their offspring would have a better mix of immune genes which equals better immune system.
4. The neurotransmitter dopamine spikes during a kiss. This is what causes the starry eyed, lovey-dovey feeling that comes from a good kiss.
5. Kissing burns around 2-5 calories a minute.
6. Holding hands and kissing reduces the levels of the stress hormone cortisol. This lowers blood pressure and increases your immune efficiency. See you should be congratulating those couples with excessive PDA on their increased immune efficiency.
7. Two-thirds of all people turn their head to the right when kissing. Go ahead and try it. Everyone asked in the Abbot lab turns their head to the right.
8. Far more men prefer the sloppy tongue kiss than women.
9. When exchanging saliva, men pass a bit of testosterone to their mate. Over weeks and months, this increased testosterone can lead to increased female libido. You know what that means guys!
10. One milliliter of saliva contains about 100,000,000 bacteria. Sexy!
Now, if that does not make you want to go out an kiss someone, I do not know what will. So good luck and happy kissing!
