From the earliest days of our evolution, humans have engaged in the mysterious and unpractical behaviour known as kissing. Science has a name for it - philematology, but what exactly is it? And more importantly why do we do it?
Scientists believe that kissing is a learned action as opposed to an instinctive one. There are tribes alive today who still don't kiss, and a more joyless group is hard to find. Best guesses have the actions origins in the feeding of babies. We were still coming to grips with our thumbs which meant that we couldn't get the lid off a jar of strained peas, so mum was forced to pre-chew her little ones food and passed it on with a kiss of sorts. In times of little food the kissing became a way to comfort if not nourish. The advent of take-away allowed us to focus on these pursuits.
The simple answer, of course, is because it feels good. The lips and tongue are packed with nerve endings and are incredibly sensitive to this sort of stimulation. Kissing has all sorts of physiological effects. Your pulse rate goes up, your blood pressure rises, the pupils in your eyes get bigger and you breathe more deeply. Kissing is physical expressions version of beef vindaloo. The pleasure centres in your brain become active as it reacts to the effects of excitement or surprise and a good kiss should be a reason for both. There are even motoneurons that are designed to let you work in the dark to maintain your relative position to this soft feeling of goodness.
It is never too late to be a good kisser. Be the bestest kisser out there. :)
Yeah. It's an old video. Still it is very yummy... Enjoy.
