Why is a person's right hand more flexible than his left? What causes left handers?

The brain is your own brain. Scientific research has shown that the brain is divided into the left hemisphere and the right hemisphere. The left hemisphere is in charge of all activities on the right side of a person. Generally, the left brain has the functions of language, concept, number, analysis, logical reasoning, etc.; the right hemisphere is in charge of all activities on the left side of a person, and the right brain has the functions of music, painting, spatial geometry, imagination, synthesis, etc.

Most people are used to writing with their right hand and holding chopsticks. Most people's right hand is more flexible than their left hand. If not, we often call them 'left-handed'. Why is the right hand more flexible than the left? This is not only a habit, but also related to the functional division of the left and right hemispheres of the human brain.

Scientific research shows that the function of each part of the two hemispheres of the human brain is not the same, and there is a division of labor. In general, the left hemisphere is responsible for the movements of the right body, while the right brain is responsible for the movements of the left body. Specifically, the left brain dominates people's language and related thinking activities such as reading, writing, listening, speaking, calculation and oral memory, while the right brain has great advantages in memorizing graphics, grasping space, music, art and technology. Because a large number of people's thinking activities are more concentrated in the left brain, the left brain is used more frequently than the right brain. Therefore, the right hand and right eye, as the objects of left brain domination, are relatively more used than the left hand dominated by the right brain. If you understand this, you can understand why there are more right-handed people and less left-handed people.

However, if you are left-handed, don't worry about it. Some research results of scientists show that left handers are beneficial to the development of human right brain. Under certain conditions, they may be smarter than ordinary people!
