Why do most people write with chopsticks in their right hand?
In the long years, people often use their right hands. Even sometimes children write with their left hand or eat with chopsticks, and teachers and parents always ask him to change. Gradually, the phenomenon of "right-handedness" is not only an acquired habit, but also an innate inheritance. Someone once did an experiment: put a four-month-old baby on a chair for a period of time every day. There were many toys in front of the chair. It was found that he held the toy *** 124 times with his hand, 74 times with his right hand and 50 times with his left hand. Later, the number of times the baby used his right hand gradually increased, so that when he put the toy next to his left hand, he also used his right hand to get it.
In the human body, the neural pathways leading to the brain cross halfway, that is, the right hand is managed by the left hemisphere of the brain and the left hand is managed by the right hemisphere of the brain. Because people often use the right hand, the sensitivity of the left hemisphere is slightly higher than that of the right hemisphere, which in turn urges people to use the right hand more, making the strength of the right hand gradually greater than that of the left hand.
