The kiss is a universal language that transcends time and boundaries. Decades ago, anthropologists estimated that over 90 percent of cultures practiced the custom, and with the rise of the Internet and ease of travel in the 21st century, it’s fair to assume that nearly all of us are doing it. Today we see kissing practically everywhere. It is a perfect example of how both “nature” and “nurture” can complement each other to create a single complex and variable behavior. Humans seem to have an instinctive drive to kiss, but the way kisses are expressed is influenced tremendously by individuals’ culture and personal experiences. Yet unlike other human behaviors, science has barely begun to put kissing under the microscope despite its clear evolutionary and personal significance.
