Of grade, the simplest answer is that humans kiss because it just feels expert. But there are people for whom this explanation isn't quite sufficient. They formally study the anatomy and evolutionary history of kissing and call themselves philematologists.

Still, most people are satisfied with the caption that humans buss because it feels proficient. Our lips and tongues are packed with nerve endings, which assist intensify all those dizzying sensations of being in honey when we press our mouths to someone else'southward. Experiencing such feelings doesn't usually make united states of america think too hard almost why we kiss — instead, information technology drives us to discover means to practice information technology more than oft.
