They say we learn something new everyday, and if anyone wants to refute me, well I certainly am going to teach you something new today. Let’s talk about kissing. I stumbled upon this video on YouTube that talks about the scientific reason of why we kiss, which got me thinking of why I have never wondered this before… Why do we kiss?
Evolutionary psychologists believe that our action of kissing could have come from kiss-feeding or the transferring of food from one mouth to another like what birds do for their babies. Kiss feeding can provide iron, protein, carbohydrates, and zinc- things not always found in breast milk! So, kiss feeding “shows a level of trust and intimacy.”
Your saliva also shows a lot of things about yourself like your how healthy you are. Also, by kissing, you can “taste” another person’s hormones which might equate being a good kisser, and “tasting good,” as being a biologically good mate. Being able to select a physically fit mate would have allowed a person to reproduce and survive evolutionarily!
Other facts that I got from the video were:
1. The average person will spend 21,160 minutes kissing during their lifetime.
2. The world record for the longest continuous kiss is 58 hours, 35 minutes, and 58 seconds… Wouldn’t a person have died from lack of oxygen by that time?
3. A “passionate kiss” burns 2-3 calories per minute….this could be a new form of exercise!
4. Kissing more often is correlated with a decrease in bad cholesterol and stress….Now I know what I need to do during finals week!
5.Our white sclera that surrounds our eyes is not just a coincidence! It actually may help us “ascertain the direction of someone else’s gaze at a glance.”
Honestly, I am a little skeptical about fact #1, but hey, I sincerely hope it’s true! Check out the video below to learn more about the theories of why we kiss!
