Why Do We Kiss
Hey, Vsauce, Michael here. Attachment of two people's lips kissing. The average person will spend about 20,160 minutes of his or her life kissing. And the worldrecord for the longest, continuous kiss is 58 hours 35 minutes and 58 seconds.But why do we kissé I mean, if you think about it, it seems kindof weird.righté I mean, sure, today kissing represents peace, respect, passion, love.But when the first two people in human history kissed, were they just kind of being grosséWell, let's begin with what we do know: kissing feels good and it's good for you.
A passionate kiss burns about 23 caloriesper minute, and releases epinephryn and norepinephryn into the blood, making your heart pump faster.Kissing more often is correlated with a reduction of bad cholesteral and perceivedstress. But these positive effects didn't become widespread by accident. Why did brainsand bodies that love kissing become so commoné Well, a popular story holds it that Pacman'sshape was inspired by the shape of a pizza with a slice missing. But Toru Iwatani, thecreator of Pacman, admitted that this was only halftrue. Pacman's shape was also inspiredby rounding out the shape of the Japanese character for quot;mouth.quot; And it's mouths andPacman's favorite activity, eating, which
together bring us closer to the heart of the kiss. Evolutionary psychologists have argued thatwhat we know today as quot;kissingquot; may have come from quot;kissfeeding,quot; the exchange of prechewedfood from one mouth to another. Mother birds are famous for doing this, and many primatesare frequently seen doing it as well. Not that long ago, it was common between humanmothers and their children. In fact, before commercially produced or DIY babyfood instructionswere readily available, it made a lot of sense. Recently, Alicia Silverstone uploaded a clipof herself mouth feeding her child. It seemed strange to some people, but even though, yeah,it exchanges saliva, which, like any contact
with an infant, can transfer pathogens, healthymothers and healthy children can benefit from the fact that kiss feeding provides nutrients.Carbohydrates, proteins, iron and zinc, which are not always available in breast milk. Plus, an adult saliva can help predigest the food, making vitamins like B12 easier for the baby to absorb. So, mouthtomouth attachment has a historyof intimacy, trust and closeness. Your saliva also carries information about who you are,your level of health, and mucus membranes in our mouths are permeable to hormones liketestosterone, making a kiss a way to tastetest a potential mate. A good kiss can be biologicalevidence that your kisser might be a good mate.
So, as a strategy for mate selection, prehistoricpeople who enjoyed kissing, and did it more often, may have made better decisions, pickedbetter mates, reproduced more successfully, and, eventually, become the norm. Giving us.us,people who love kissing. Any infant could have seen those benefitscoming from a mile away, even though an infant's vision isn't that great. From birth to fourmonths, babies can only focus on things about 810 inches away from their face which, notsurpisingly, is about the distance to their mother's face while breast feeding. So, faces, especially those looking rightat us, tend to be the very first things in
our lives we can focus on and see clearly.This might explain why we are so good at detecting faces. Humans are off the charts when it comesto this, in fact, we tend to see faces even when there aren't any.It's called quot;pareidolia.quot; Because humans are so cooperative, it makessense for us to be good at recognizing faces. And, more importantly, detecting when someoneis looking directly at us and clearly expressing when we are looking at someone else. A predator who lives by not being seen needsa gaze that's less obvious. In fact, research has shown that our surprisingly white scleras,the area that borders the iris, isn't just
