Everyone's lips are tilted to the right and this is the reason

What is the reason behind this? Simply because you are right-handed, or a social habit.

If you're not a "genuine" FA, you may have experienced kissing and kissing. But notice this, most of you have experienced it, you tilt your head to the right, right?

Most of the kisses you've ever experienced, you tilt your head to the right.

In fact, science has made assumptions about our brains. Each person's brain has 2 halves, but we usually only prioritize using one side. And also according to many experiments, that's right.

Kissing too, most of us tilt our heads to the right. But the problem is that doing it is instinct, or is it because we learned through TV, movie?

The results show that 2/3 of the respondents always tilt their heads to the right. In particular, for people who actively perform kisses, right-handed people will tilt to the right and left to tilt left. As for the person who is kissed, no matter which hand they are, they will tilt in the direction that the active person is inclined.

This proves that, despite cultural differences, social norms, people still have many similarities in their habits. Just tilting your head to one side when you kiss seems to be determined by the habit of brain movement, like the right or left-handed person. The number of left-handed people only accounts for a small part of society, so it is clear that the person leaning to the left is also less.

Despite cultural differences, social norms, people still have many similarities in their habits.

According to experts, perhaps the reason lies in the level of hormones at each hemisphere and neurotransmitters are unevenly distributed between the two hemispheres of the brain . Examples include dopamine - rewarding hormone, or testosterone - male sex hormone. This difference creates a tendency for us to tilt our heads to one side.
