Right hand years, left hand flowers

Modern scientific research shows that the left and right hemispheres of the human brain have different functions. It is generally believed that the main function of the left hemisphere is logical reasoning and language expression, which is related to language, numbers, concepts, analysis, etc. The main function of the right hemisphere is spatial and image thinking, which is specifically reflected in the abilities of music, rhythm, painting, intuition, sense of space, integrity, imagination and synthesis. At the same time, some studies in recent years have also found that in people with left brain injuries or diseases, the right cerebral hemisphere is dominant due to the damage, resulting in the "Rain Man" phenomenon (also known as the "idiot savant", featured in the 1988 movie " After "Rain Man" won the Oscar, it was also commonly known as "Rain Man" (called "Savant Syndrome" in the medical community). The educational community is also discussing issues such as "quality education and right-brain development" and "right-brain revolution." Many art masters (such as Leonardo da Vinci, Michelangelo, Picasso, etc.) are accustomed to using their left hand, so some researchers believe that it is the function of the right brain that leads to artistic creativity. Let us not consider the scientific research aspects for the time being, and just judge from our common sense. If we pay attention to exercising the right brain in daily life, even if it is not beneficial to us, at least it will not be harmful. If we can really achieve a balance, communication and complementarity between the left and right brains, and possibly even improve the efficiency of the human brain to a greater extent, then we will definitely gain more than just the joy of "accidentally inserting willows and willows". In recent years, I have gradually figured out a plan to exercise my left hand in daily life. I hope to discuss and communicate with interested colleagues, improve together, and activate the brain.

1． Eat with your left hand. The dining habits of Chinese people that are different from those of Westerners is the use of chopsticks. Some people once proudly attributed this to one of the reasons why Chinese people can achieve good results in world-class intelligence competitions. But we should also see that compared with the "left and right fighting" of Westerners using knives and forks, we have lost the most common opportunity to balance the left and right hands. Therefore, it is recommended to gradually train your left hand to use a spoon and eat with chopsticks.

2． Brush your teeth with your left hand. This is also a great opportunity to exercise your left hand and activate your right brain. The initial brushing movements with your left hand must be gentle. Excessive movements can easily damage your gums and cause you to lose interest and confidence in brushing your teeth with your left hand. Even when you are able to use your left hand to brush your teeth proficiently, you will still find a very interesting phenomenon: your right hand will always make forceful movements, or it will be placed very stiffly at a certain angle, making it difficult for you to brush your teeth with your left hand. Brushing your teeth with your right hand is as easy and natural as your left hand.

3． Use scissors in your left hand. Since most of us are right-handed, the scissors we usually see are "right-handed scissors", that is, the right side of the scissors is placed upward in order to correspond to the adduction function of the thumb. Because we can't find "left-handed scissors" for the time being, when using conventional scissors with the left hand, only the left thumb can be used with inward and downward force to achieve the purpose of cutting paper and cutting lines.

4． Use the mouse with your left hand. With the improvement of living standards, the popularity of computers is also getting higher and higher. We can hardly do without computers at work and off work. It is recommended that you practice using the mouse with your left hand. First, observe whether your mouse is symmetrical. Since there are many left-handed people in foreign countries, most mouse products from international brands such as IBM, Microsoft, and Logitech are symmetrical. In the Windows operating system, the mouse option in the control panel can change the left and right buttons so that it becomes a left-handed mouse. There are at least the following two benefits of training your left hand to use the mouse: 1. Reduce carpal tunnel syndrome caused by long-term use of the mouse; 2. Extend the service life of the mouse by at least 50% (I used to have problems with the left mouse button not working It’s such a pity to think about the history that was thrown away!)

5. Write with left hand. When watching foreign movies and listening to lectures by foreign teachers, we often find that foreigners use their left hand to sign, write, and write on the blackboard. We should also practice it. Writing with the left hand can be divided into two aspects. On the one hand, we use our left hand to write from left to right, which is to try to use the left hand to replace the functions of the right hand. Although the writing was so ugly at first, in fact, when I first learned to write with my right hand, it may not be as good as it is now. On the other hand, we use our left hand to write mirror-image characters from right to left. That is, after writing, we set up a mirror on the left or turn the paper to the other side and look at the light. What we see is the orthographic character. I personally suspect that this may be the most effective way to promote communication between the left and right brains, and it may also be a real use of the right brain. When you calm down and write mirror words easily, you will definitely be surprised why such an interesting phenomenon occurs.

6. Mobilize the left hand and left limbs to participate in sports activities. You can practice shooting the ball with your left hand, shooting with your left hand, playing badminton and table tennis with your left hand, and kicking the ball with your left foot. Finally, practice throwing things with your left hand and conduct whole-body coordination training.

7． Spin the medicine ball with your left hand. Don't think that spinning two fitness balls is just for beach tycoons in the old society or the elderly today. It's not a bad idea for us to use it to exercise our left hands. If you think the fitness ball is too heavy to carry around, you can use two suitable walnuts instead. Moreover, the edges and corners on the walnuts may have a better stimulating effect.

8． Turn pen. I often see people turning the pen in their hands in a dizzying manner. Although I personally do not agree with this behavior, if you are particularly fond of turning the pen, I suggest you start practicing it with your left hand again. It's annoying when it keeps falling to the ground.

9． Starting from the functional positioning of the right brain. Russian medical experts have achieved significant results by using music to treat premature and mentally retarded infants. Americans found that listening to background music significantly improved memory for subjects. A survey found that more than 90% of senior executives in the U.S. Congress and Fortune 500 companies received music education in their childhood. Because the right brain is related to music, rhythm, painting, intuition, sense of space, integrity, imagination and synthesis, etc., listening to more music, being more exposed to painting, and imagining more may also be a good way to develop the right brain.
