Kisses have a right to take an honorable position on the list of functions of the human brain. Every human being living on planet Earth enables this function throughout their lives: women kiss men, men kiss women, Fidel Castro kisses Kim Jong-Il, etc. It is generally believed that one does not have to be smart to learn how to kiss. However, the issue is worth being analyzed from the scientific point of view.
