We all remember that first kiss a person who made us feel special the butterflies in our stomach as we leaned forward to touch lips and share a moment of intimacy this human ritual of touching lips and kissing has been around for generations and it has different meanings depending on the culture and context everything from love, passion, romance to sexual attraction but we also share 80 million bacteria when we kiss each other well, that's quite an exchange for a moment of passion so what's it all about that's what we'll be looking at today in this episode of the infographic show why do people kiss it may seem that kissing is something that everyone does but analysis suggests that less than half of all cultures actually do it and kissing is also very rare in the animal kingdom.
So, what really motivates us to kiss and if it was really meant to be everyday behavior. Why don't all humans and some animals do it according to the BBC a study of kissing preferences which looked at 168 cultures from around the world only 46% of those cultures kissed for romantic or loving reasons previous estimates had put the figure at 90%. so romantic lips slapping looks to be less common than we might have imagined and why the lips anyway. I mean we could show romantic passion by rubbing foreheads by giving high-fives or by turning back to back and bumping butts there are endless different ways, we could touch bodies to show our romantic gesture. you may have heard the term Eskimo kiss also called a nose kiss or nose rub this is where you press the tip of your nose against another's nose as a friendly greeting.
As an example women subconsciously prefer
the scent of men whose genes for certain
immune system proteins are different from
their own because this kind of match could
yield offspring with stronger immune systems and better chances for survival there have been a number of studies on this and the study to indicate that chemical signals play a role in attraction was conducted by Claude wet content when T years ago Wed contend
his team collected DNA samples from 49
female students and 44 male students. He asked the men to wear Khan t-shirts two
nights in a row to keep the shirt in a plastic bag to use perfume free detergents and soaps and to avoid smelly rooms smell producing foods as well as activities like smoking and sex that can create odors as for the women they were given a nasal spray to use for two weeks before the test to protect their nasal membranes from becoming infected and they were even each given a copy of the Patrick Susskind novel perfume to make them more conscious of odors.
Women then sniffed the worn t-shirts of men to get a sense of which smelt the best to test the results researchers compared the DNA of the women and the men to see if a pattern had evolved. They found that women didn't just choose their favorite scent. Randomly they preferred the scent of a man whose major histocompatibility complex or MHC which is a series of genes involved in our immune system was different from their own. When a couple who have different MHC produced a child there is a better chance of the newborn being strong and healthy.
