Right-handers also tend to head right

We people have a privileged side for many things. Whoever writes with his right hand tends to turn his head mostly to the right while kissing.

On which side does the head lean when kissing?

However - writes researchers in the scientific journal Scientific Reports - this applies only to the one who starts with the kissing. The more passive Kisser, on the other hand, adapts to the more active kisses on his head tilt so that there is no collision.

For their study, the researchers were traveling in Bangladesh and have examined 48 heterosexual couples. They chose Bangladesh because kissing is a privacy that does not happen in the public and can not be seen in the media. The researchers wanted to ensure that they examined the natural behavior of their subjects.
