Left hand training will be smarter?

The left -handed person is more agile than the right -handed person. According to statistics, 15 children in the French swordplay team have 8 left -handed children. For a while, half of the members of the Chinese table tennis team were not right -handed ... not only more active, if you work hard to practice left hand, you will be smarter!

The brain is divided into 2 hemisphere: left hemisphere and right brain hemisphere. Each side of the brain has the function of tendon on the other side of the body. The left hemisphere dominates most of the right body activity, has a special relationship with the development of language, called "language dominance hemisphere". Here, the pulses feel the highest gathering to form language signals and abstract concepts. Therefore, the function of the left brain hemisphere is inclined to the stage of cognitive reason, and forming abstract thinking of people.

The right hemisphere dominates the left half of the body. Through the adjustment, the pulses feel the specific image of all things, people, space and time. Therefore, the hemisphere must be more about the stage of emotional awareness, called the "hemisphere that dominates without words".

The left hemisphere controls the right hand, the right brain hemisphere controls the left hand. If we exercise (especially fingers), we can stimulate brain cells in a certain area, causing the brain to grow. That means, if someone often uses his right hand, the left brain will grow more and vice versa.

The process from visual to reactions in the right hand and left hand is different. In the right -handed person, the nerve line has the form: "Right hemisphere - the left hemisphere - the right hand". In the left -handed man: "Right hemisphere - left hand". Obviously, information from visual to movements in the left -handed person is less than a stage, so he reacts faster than the right -handed man.

The right -handed person, every time he used his left hand, felt embarrassed, did not even do a small thing like holding chopsticks.
