About 10 percent of the human population is left-handed people. But many people who take turns using the left and right hands while doing various activities. Yet since ancient times, a lot of left-handed people are discriminated against. Various related myth was developing this left-handed.
Lefty looks awkward because much of the equipment in the world, such as sports equipment and musical instruments, which are designed for those who are not left-handed. A simple example, consider just a camera button that is located on the right. For the left-handed, the button layout is certainly difficult to make lefties become awkward.
But the more serious problem is that many tools and heavy machinery which could be dangerous for lefties. This is because they are difficult to reach the on and off when operating the machine.
Even for writing in general is more difficult for left-handed people. Fortunately the modern world to be 'more pro' on the left hand among more active. Computer keyboard arranged with the QWERTY system. 56 Percent of keystrokes made with more emphasis on the use of the left hand. In addition 3,000 English words can be typed entirely with his left hand, and only 300 words were fully typed with the right hand.
The positive side left-handed people, many of whom became quickly adapt to many things that are designed for people who use the right hand. Sometimes, living in the 'world of the right hand' would be a boon for those who are left-handed.
According to the Victorian government in the Better Health Channel, profits lefties in the field of sports is when dealing with people who move with the right hand. For left-handed people often give a 'surprise' for right-handed opponent.
Is it true that left-handed people More Smart?
Many myths about lefties thrive. The most common is that left-handed people believed to be smarter, more artistic so many believe they fit into the architect and musician. It is based on the idea that the right side of the brain controls the left side that tend to be associated with music and creativity. While the left side of the brain generally associated with math, logic, science, and language."This is completely incomprehensible," said Dr. Clyde Francks from the Wellcome Trust Centre for Human Genetics, University of Oxford.
"We're really at the very beginning of understanding what makes the brain asymmetrical," he added.
In fact, there are no studies that really show that left-handed people are smarter or more artistic. In the largest IQ test that was held in the UK, where 90 thousand people are involved, the result is less than one percent of people are left-handed higher scores than right-handed.
"What we know is that left-handed people tend to have more distribution activities in the two hemispheres of the brain," said Francks. While the right-handed people tend to be more active parts of the brain left.
Therefore, people believed better lefty in organizing large amounts of information. They also tend to be multi-tasking because both sides of the brain used to communicate more efficiently.
Perhaps this is enough to explain why the research at Johns Hopkins University in 2006 in the United States found 10-15 percent of left-handed people earn more money than those who are right-handed. Yes, many left-handed people are multitasking.
However, it took a lot of research about left-handed people. So far, research conducted sample was very small, but it still influences the social and biological variables so that appropriate conclusions are often difficult to obtain.
In addition there are many theories about the southpaw who has not been proven. For example, about the life expectancy shorter left-handed people, also the opinion that left-handed people are more susceptible to colon cancer or breast cancer.
"Several studies have shown that learning difficulties, epilepsy and autism is more common in left-handed people," notes the Better Health Channel.
However, other researchers could not confirm this discovery. Knowledge have recently demonstrated that the use of the more dominant hand is not related to the ability to learn.
A study at Oxford University recently discovered a gene that can increase a person's chance of being left-handed at the same schizophrenic. But according to Dr. Francks, people do not need to worry about these findings. Because there are many factors that make a person experiencing schizophrenia.
