Maybe we can leave medical problems to experts in brain nerve and cognitive behavior to study. However, here are some things that have proved to excite supporters: 1. There are always some unique ideas that are different in some ways. Left-handers often think of shaped images in their minds before writing or drawing, and many left-handers will try their best to reassemble the bits and pieces they can't remember into pages of pictures and remember them. Just like Buruli, the father of modern architecture, in the14th century, he could put forward digital graphics to explain how to build Florence Dome Cathedral. "I have thought about what it will look like when it is finished." He said that he beat the bidders from all over Europe. Some people think that this ability explains why many left-handed people are outstanding in issues involving space and art. Strong mathematical ability, strong visual perspective and strong spatial ability are conducive to the development of mathematics and architecture. 1990 Annet &； Manning's research found a correlation between right-handedness and lack of mathematical ability. 3. If a right-handed person has a close relative (such as a brother or sister) who is left-handed, then the right-handed person's memory is better than that of a person whose whole family is pure right-handed. A study at the University of Toledo, Ohio, found that right-handed people whose close relatives are left-handed show strong situational memory (such as where the keys are conveniently placed after entering the door). Although the semantic memory stored in the database (such as the starting and ending years of World War II) is poor, it may be because the information itself has a left brain and the temporal and spatial background information of the event has a right brain, so combining the two can enhance the situational memory. Researchers suspect that the corpus callosum that may connect the left and right brains is very large, indicating that your brain structure is a mixture of the left and right halves. 4. Left-handed people seem to perform well in sports that require quick response and correct spatial judgment. People who are more flexible and stronger with their left hand, left foot and left eye, especially in tennis, football and golf, often perform better than others. Tennis celebrities such as Naratinova, Connors and mcenroe. Left-handed people also have an advantage, because right-handed people are not used to playing with him. Some left-handers can even switch to the right hand to swing or swing when necessary, which most right-handers can't do. Like fencing, a sport in which two people fight each other, left-handed people also have special advantages, and the proportion of winning the championship is very high. 6. People with strong left hand, strong right foot and strong right eye may have the problem of uncoordinated integration, which especially affects the swing action, because the line of sight may sometimes be limited. But it is beneficial to gymnastics, running, basketball and other games that require a strong sense of physical balance. 7. It is much more difficult for a right-handed person to do things with his left hand than for a left-handed person. Moreover, left-handed people are more willing to listen, accept or consider other people's opinions and ideas. This is related to the fact that left-handed people have been adapting to the environment all their lives, learning when to cross their bodies with their left hands or when to switch to their right hands, and overcoming difficulties is related to constant practice. There are many other related studies, but they have not reached the final stage, including: 8. Poor autoimmune system, including asthma, migraine, diabetes, autism (65% of autistic patients are left-handed), learning disabilities, paranoia, easy to go astray. However, in 199 1, another study refutes this theory. 9. The School of Medicine of the Royal Free University of London recently suspected that left-handed people are twice as likely as right-handed people to suffer from inflammatory intestinal diseases (such as Crohn's disease, with symptoms of pain, severe diarrhea, intestinal bleeding, weight loss and fever). 1860 French surgeon Brock said that the left brain of left-handed people is underdeveloped, which affects their language ability. However, some people retort that it is too simplistic and irresponsible to divide the relationship between hand and brain in this way. In the1970s, many studies found that most left-handers had the same specialized language area in their left brain, just like others, and only a small number of left-handers had different language areas. So using the left hand will not cause literacy or arithmetic difficulties. If the child has a problem, find out the real problem. 10, American psychologists Kong Rong and He Qi suspect that left-handed people will live nine years less than right-handed people (66 years vs.75 years). When this statement came out, everyone was in an uproar. Later, it was refuted by the research community that they used fallacious research methods to forcibly support their assumptions (left-handed people drive cars designed for right-handed people, operate backhand, and respond in an emergency). Kong Rong and He Kun asked their families about 1000 car accident victims in a small town in southern California, whether the victims were left-handed or right-handed, but only three of them became left-handed, and there was no way to prove whether these three people really died in a car accident because of being left-handed. 1 1. Because living in a right-handed society, left-handed people are more adaptable to stress. In addition, left-handed people often have distinctive opinions, good imagination and overall grasping ability. Based on the above advantages, left-handed people will obviously have advantages in their career development, work hard and make great achievements.
