After all, there are a few people who are used to using their left hands, but scientists recently said that the future situation may be very different, because the number of left-handed people is increasing rapidly.
After 15, the number of people is expected to increase to 10 billion.
Statistics show that 1 person in the world is left-handed, accounting for 600 million people; By 2020, the number of left-handed people is expected to reach 654.38+0 billion. Russian Pravda said that scientists now have a new theory about left-handedness. Dubov, a professor of biology, said that the number of left-handed people born in 2005 was twice that of 1990. He believes that human beings are changing, which is a good phenomenon, because human beings have not degenerated, but become more perfect.
Research shows that people who are used to using their left hands have higher IQ than those who use their right hands: 1 out of every five outstanding people are left-handed. Many people with extrasensory abilities are left-handed. Left-handers, once considered a defect, have now become a symbol of genius. Throughout the ages, many great figures who changed the history of Gankun were left-handed, and the role of left-handed people in contemporary political and economic life was far higher than their proportion in the population: former US President Bill Clinton, Cuban leader Castro, Queen Elizabeth II and Prince William; Famous painter Da Vinci, comedian Chaplin, sexy actress Marilyn Monroe; Natural scientist Einstein, Microsoft founder Bill Gates and even terrorist tycoon Osama bin Laden are all left-handed.
The fetus in the mother knows the future trend.
Experts have not clearly explained the phenomenon of left-handedness, but they found that the fetus formed the habit of being either left or right in the mother's body. Using special ultrasonic imaging technology, they found that if the fetus is trying to suck its left hand, it will be left-handed in the future. Experts say that there will be some functional changes in the middle and late stages of infant brain development. Because the right hemisphere not only controls the left hand, but also determines the ability of people to speak and write in the future.
When the left hand began to play a leading role, the human brain has undergone significant changes. Of course, if this change is not strong or not completed, this person will be indifferent to his left and right hands in the future. Russian President Vladimir Putin is a good example. He seems to be used to using his right hand, but he wears his watch on his right hand and often takes things out of his right pocket with his left hand. Left-handed people may be related to their special genes, and they are also hereditary. However, there are some exceptions. A recent study of 20,000 people shows that left-handed people are usually born to pregnant women over the age of 30, and they are six months premature.
Important revelation: we should develop the right brain more.
With the popularization of computers today, many things can be done with computers. However, this does not mean that computers will become the new owners of the earth one day. The reason is that the work of computer only involves the logical thinking function of human left brain, while the functions of thinking in images, perception, premonition and creativity belong to human right brain, so far it is difficult for computer to "execute". An important revelation of left-handed phenomenon is how to develop the function of the right brain.
The function of human right brain can only be cultivated and exerted by human beings themselves. The development of the right brain belongs to non-intellectual development to a great extent. Non-intelligence factors include motivation, interest, emotion, will, personality and other factors. People with developed right brain function not only have creative thinking, but also are observant and easy to cooperate.
Consciously use "left"
How to develop the function of the right brain? The right brain dominates the left hemisphere and controls the movement of the left hand; The movement of the left hand and the left half-body organs can also stimulate the right brain. Consciously moving the left hand, left leg, left eye and left ear, especially the fingers of the left hand and left hand, can produce benign stimulation to the cerebral cortex and effectively develop the function of the right brain.
The left brain is in charge of language and makes logical reasoning according to the existing knowledge, which is a very important function. However, the language produced by the left brain is generally lack of inspiration and it is difficult to come up with new theories. The function of the right brain is to understand, imagine and expect. When we encounter some puzzling things, if we make good use of the right brain function, the innate information in the right brain will play a role, giving people inspiration and solving problems easily. However, while developing the right brain function, we should also pay attention to the exercise and application of the left brain function to make the brain develop in a balanced way.
Phenomenologically, the most striking feature of left-handed people is that they tend to use their left hands.
This is especially inappropriate in a world where most people use their right hands.
A man with chopsticks in his left hand appeared on the dining table, leaving a large space on his right side, and a collision accident was inevitable on his left side.
From the perspective of observing things, left-handed people and right-handed people are different.
In the unconscious state, draw casually, draw the profile of a person or an animal, and the left-handed person draws his face to the right. Draw a three-dimensional picture of the house, which extends to the right. Draw a cross and a circle. Left-handed people often write counterclockwise. Right-handed painting is often the opposite.
Some studies show that left-handed people have better visual adjustment ability under water. There are also some reports that the puberty of left-handed people is 4-5 months later than that of right-handed people. Some people find that the structure of left hand and right hand is different. A study shows that the ratio of left-handed ring finger to index finger is much longer than that of ordinary people. What is the internal reason is still a mystery.
It is worth noting that left-handed people, who account for an absolute minority of the population, have amazing energy in social, political and economic life. When people are surprised by the emergence of left-handed presidents in the United States at the end of the 20th century, when people are surprised by Bill Gates planting Microsoft flags around the world, and when people are surprised by the whirlwind of Nintendo game software in Shigeru Miyamoto, people can't help asking: What does this have to do with the characteristics of left-handed?

The characteristics of left-handed people may stem from the brain structure.
Different from ordinary animals, the human brain not only has the function of directly or indirectly regulating the physiological activities of various organs and systems of the body, but also becomes an organ of thinking and language, enabling human beings to transcend the category of ordinary animals and form a society in productive labor. In this sense, the difference between human beings and ordinary animals lies in the difference of brain structure.
The human brain is divided into two hemispheres, the left hemisphere and the right hemisphere. The wonder lies in the different division of labor between the two hemispheres. The left hemisphere dominates the activities of the right hemisphere and has the functions of language processing, abstract thinking, logical reasoning, numerical operation and analysis. The right hemisphere dominates the activities of the left hemisphere, focusing on rhythm, imagination, overall image, spatial concept, music and so on.
The two hemispheres of the brain are connected by the corpus callosum, that is, transverse nerve fibers connecting the two hemispheres. The corpus callosum is responsible for the transmission of nerve information between the two hemispheres of the brain. Left-handed people prefer that their corpus callosum is more developed.
The deviation of human body movements will naturally stimulate the development of the corresponding hemisphere of the brain and have a significant impact on human ability. Left-handed people often use their left limbs, and the right hemisphere receives relatively more stimulation, which makes left-handed people tend to think in the brain.
Therefore, relatively speaking, left-handed people may have stronger perception, sense of space and ability to grasp the overall situation. A well-developed corpus callosum also makes left-handed people relatively more agile. All this has been fully reflected in many excellent left-handers.

Left-handed people have stronger spatial awareness and thinking ability in images.
The right brain has the ability to recognize space and images, that is, the ability to think in images, which makes the right brain at the forefront of the brain's perception of the world and its perception ability is stronger. As a physicist, Einstein seems to have a well-developed left hemisphere. However, through in-depth study, he found that he could not pass French at school. On the contrary, his hobbies are playing the violin, drawing, sailing and imagining games.
Einstein attributed many of his scientific ideas to his imaginary right brain activity. It is said that one summer, he fell asleep on a hill, dreaming that he rode a light beam to the distant extreme of the universe and found himself "illogically" returning to the surface of the sun. He suddenly realized that the universe was originally curved and the knowledge of "logic" he had learned before was incomplete.
Einstein transformed this picture into language, and the numbers, formulas and words written down became "relativity".

Left-handed people are more imaginative.
1968 Picasso was 87 years old when he took over the illustration of the Italian Renaissance prose poem celestine. Although life has gradually come to an end, Picasso's artistic exploration spirit has not diminished.
Picasso said: "The painter broke what he saw in his eyes and gave it another life. He must see his own truth through the real world in the eyes of others. " Because of this, Picasso, who rarely copied pictures, said, "I am not looking for it, but discovering it."
Picasso famously said, "Art is not truth. Art is a lie that teaches us to understand the truth. " He believes that "a painter should keep his eyes out of the cage like a goldfinch, so that his singing can be good." Perhaps it is Picasso's brain thinking characteristic of painting with his left hand that makes him a magician of modern art in the 20th century.
Left-handed people have a stronger spatial imagination, much like architects' work, designing three-dimensional objects and buildings on two-dimensional planes. In fact, left-handed people tend to perform better in these fields. 1982 According to a statistic made in Japan and the United States, the proportion of left-handed people who grow up to be artists and architects is higher than that of right-handed people.
The most typical example is that the three Italian Renaissance masters Leonardo da Vinci, Michelangelo and Raphael were all left-handed, and Shigeru Miyamoto, the master of modern video game production, was left-handed. The murals on the dome of St. Peter's church in ancient Rome are in the same strain as Mario jumping on the computer screen.
Some scholars have put forward various explanations that the president of the United States is left-handed. Leonard, a professor of cognition and education at Harvard University, pointed out in his book Spirituality of Leadership-Analysis of Leadership Style that one of the conditions for becoming a leader is that he must be able to think in a subtle way and be different from others. In the process of thinking more and seeking various solutions, left-handed people score higher than right-handed people.
He also analyzed that left-handed people are particularly prominent in conceptualizing and planning election campaigns, so there are many examples in history in which strategists turned to politics. Napoleon, Churchill and Powell, left-handed generals, abandoned armour and made great achievements in politics.
Another scholar, Colan, a psychology professor at Columbia University, wrote in the book Left-handed Syndrome: Left-handed people like to be dominant, competitive and calm. He also pointed out that in the world dominated by right-handed, left-handed people are under greater pressure, and pressure often becomes the driving force for progress, which is one of the reasons why left-handed people stand out. Some analysts show that in recent years, left-handed people have become more and more influential in high-tech fields and political circles.

Left-handed people are more agile
Left-handed agility has become a permanent topic in sports. Generally speaking, for sports that don't need face-to-face fighting, such as swimming, track and field, shooting, etc. The proportion of left-handed athletes is not high compared with their proportion in the population.
However, for those face-to-face fighting events that bring players closer in the competition, such as fencing, table tennis and basketball, the proportion of left-handed athletes in the population is much higher than that of left-handed athletes.
In fencing, the most typical fighting event, between 1979 and 1993, half of the male players reached the quarterfinals of the World Championships, and one third of the female players were left-handed. The title picture is a photo of our national fencing team training. Table tennis has been dominated by lefties for many years, and tennis has been dominated by lefties for a long time. The NBA professional basketball game in the United States is also particularly prominent.
One explanation is that the left hand is commanded by the right brain, which is responsible for sensing space and sensing functions, which makes it easier for left-handed people to exert their visual and spatial sensing functions, and to shoot faster, more accurately and more ruthlessly. From the speed of nerve transmission, from "seeing" to "moving", right-handed people take the route of "right hemisphere-left hemisphere-right hand", while left-handed people take the route of "right hemisphere-left hand".
It can be seen that left-handed people took a shortcut in the process of nerve transmission. The speed at which the brain transmits information to the left side of the body through the central nervous system is fifteen thousandths of a second faster than that to the right side, which makes left-handed people move faster.

On the other hand, the right brain also controls emotions and imagination. Left-handers are easily excited, excited and impulsive during the game, and enter the game quickly. In addition, left-handed athletes account for less, and their opponents are unfamiliar and unaccustomed to left-handed athletes, which is also their advantage.
In life, because left-handed people think more with the right brain, which originally controlled people's thinking in images and functional reflex, left-handed people will be more creative and sensitive to things around them than ordinary people. A left-handed lover may be more affectionate.

Two common problems
Now we may be able to answer two questions that people often ask. Are lefties more clumsy?
From any point of view, left-handed people are by no means more stupid than non-left-handed people. Many famous politicians, scientists and artists are left-handed, which fully shows that left-handed people are a creative group.
So, why do people sometimes think left-handed people are a little stupid? The key is that the tools we often use are all designed for the right hand. Left-handed people are quite inconvenient to use and naturally look awkward. If you don't believe me, right-handed people can try to cut a button on their shirts with scissors in their left hand. People may not lack skin and meat, and it is inevitable that clothes have holes.
Are lefties smarter? Uccess00 1.cn success network
This question may not be accurate enough. It may be more appropriate to say that left-handed people have their own characteristics and strengths. If they are good at benefiting others and benefiting themselves, they may achieve greater results. Left-handed people are characterized by using their left hand more, which stimulates the development of the right brain, or because the right brain is the dominant hemisphere, they are left-handed. Therefore, left-handed people have a good sense of space and strong perception.
Because the right hemisphere is in charge of rhythm, music, color, space and left limb activities, relatively speaking, left-handed people have a strong sense of rhythm, a good sense of spatial balance and are more sensitive to color. If the success of some famous left-handed scientists, musicians, painters and athletes is related to their left-handedness, it is better to say that they are better at and give full play to their own specialties.
