First of all, use your left hand. People's left and right brains cross and control their left and right bodies. When brushing teeth, eating, playing badminton and basketball, it is helpful to have a left hand as much as possible.
Second, remember more and make more. People's right brain is the birthplace of creation, and it is responsible for storing information such as images and emotions. People with rich emotions often have a developed right brain, and they can make full use of the storage space of the right brain by remembering things.
Third, give consideration to both sides and coordinate exercise. Always do some coordinated actions with your left and right hands. Unilateral exercise can not only promote their own healthy development, but also have harmful effects, resulting in unhealthy consequences, such as the obvious gap between left and right body reaction speed, unbalanced emotional and personality development.
