VIDEO : Which Way Do You Lean When You're Kissing?

Scientists have realized that humans may be hardwired to kiss their partner by leaning to the right. Three different universities all worked together to study 48 married couples who were asked to keep track of which way they leaned when they kissed. Since each individual wrote up their own report of the kisses, scientists were able to determine that most of them lean towards the right. Besides the way people kiss, the study also showed that men were 15 times more likely than women to initiate a kiss.
