Kissing to the right

Onur Gunturkun (a psychologist at Ruhr University), after spying on kissing couples in US, Germany and Turkey, found that when couples kissing, 65% tilt their head to the right, while 35% went left.

Here is the explanation from Onur Gunturkun: before born, we as fetuses in the womb begin to tilt heads, usually to the right. Most of us the grow to favor the right hand, foot, eye and ear.
