To kiss your partner is always special, but a study has revealed that more than two-third of humans are hardwired to tilt their heads to the right when lip-locking their spouse, while adding that men are about 15 times more likely than women to initiate a kiss.

Over two-thirds of the kiss initiators and kiss recipients turn their heads to the right.

It is also the first study in the world to show that the kiss recipients have a tendency to match their partners' head-leaning direction.

Researchers at the Universities of Dhaka (Bangladesh), Bath (UK) and Bath Spa invited 48 married couples to conduct the same.

The study suggested that the kiss recipients have a tendency to match their partners' head-leaning direction in order to avoid the discomfort of mirroring heads.

It suggests that the act of kissing is determined by the brain splitting up tasks to its different hemispheres - similar to being either right or left-handed - specifically the functions in the left cerebral hemisphere, located in the emotion and decision-related areas of the brain.  -- ANI
