When taking selfies, why do some people like to pat their left face?

People's left and right faces may show different and distinctive expressions and emotions. According to the hypothesis that the right hemisphere of the brain dominates emotions, the right brain has more advantages than the left brain in controlling and expressing emotions, while the left face of people is mainly controlled by the right brain, so the emotions expressed by the left face may be faster, more direct and stronger than the right brain.

The reason why humans like the left face is: 1. The human brain prefers to look at its left face, which is emotional and social. For the brain, what the left eye sees is more credible than what the right eye sees. When you stare at a person's face, it is mainly the right hemisphere of your brain (corresponding to the right hemisphere) that processes the emotions expressed by the face. In addition, the information on the left side of our body is first transmitted to the right hemisphere of our brain for processing. In other words, what your left eye sees is transmitted to the right hemisphere of your brain earlier than what your right eye sees. Therefore, the right hemisphere will rely more on what the left eye sees when reading faces. Therefore, when you look in the mirror, you will prefer to look at the left side of the mirror, which is your left side.

2. A person's left and right faces are not completely symmetrical. In the process of human growth and development, the left and right sides always play different roles. Different cells on the left and right sides perform their respective duties, forming asymmetric internal organs and human appearance. Similarly, the left face and the right face grow under the control of different cells and nerves, so even with the same genes, a person's left face and right face are not completely symmetrical, but some are obvious and some are not.

At the same time, many habits in our life will also aggravate the left-right asymmetry. For example, unilateral chewing, unilateral chin rest, side sleeping, poor sitting posture and so on. However, symmetry is of course beautiful, while asymmetry is more vivid, attractive and creative. This natural asymmetry and imperfection of the human body is like the growth and feeling brought by the expectation and regret brought by the unknown in life. It is precisely because of these uncertainties that we have a rich and beautiful life.
