left handedThey are forced to live in a world shaped for those who follow the traditional saying “things go right”. Therefore, everyday they do everything in reverse! So let’s try to answer the question: why are some people born left-handed and how do they differ from the others?

Once stigmatized and socially excluded

The issue of left-handers remains a mystery to science. For many years they were considered abnormal by an ignorant, full of prejudices society and were forced to write with their right hand by parents and teachers.

The imperatives of the Christian religion dictate the faithful not to cross himself with his left hand. A range of evidence from the religious texts suggests that this group of people is in a “dark path”.

They are 10% of the world population

One in ten people uses his left hand, which means that at least 600 million people see the events from a “left” perspective.

In the last years a rapid increase in births of left-handed children has been noted. According to the Russian Professor of Biology Alexander Dubov “the number of left-handers born in 2005 is double that recorded in 1990. Continuing this upward trend, in 2020 it will exceed one billion.”

Is it a matter of genes?

There are people who are born left-handed and others who make use of both hands. For an unexplained reason, until now the phenomenon occurs more often in boys.

According to Dr Clyde Francks, researcher at the Department of Genetics, University of Oxford, “the LRRTM1 gene holds an important role in determining the brain areas that guide specific functions. In left-handers, the left brain controls emotions and the right brain is responsible for speech. In right-handers, these are vice versa.”

The outstanding talents of left-handers

In left-handed people the right lobe of the brain is prevailing, which is associated with a high perception of sounds and colors. Therefore many of them excel in the areas of art, painting and music.

Moreover, many left-handed people have excellent memory and mathematical perception, which pushes them to engage in science and their accomplishments remain on the pages of history as great scientists. It is noteworthy that many left-handers have profound metaphysical concerns and a highly developed intuition.

In addition, three out of five children whose IQ exceeds 130% are left-handed! Also it is noted that left-handers often reach the top of professional success faster than their colleagues.

The negative aspects of being left-handed

Being left-handed may have a series of advantages, but to complete the portrait all the elements are necessarily, even if they are negative. According to research left-handers live from a few months to nine years less than right-handers, which has to do with the fact that they are more prone to fatal accidents.

Research held in the Abetray University and led by Dr Lynn Wright came to a number of conclusions: left-handed people feel more embarrassed than others when attending important social events. The embarrassment lies in the facial expressions and body language. Their anxiety shows more intensely: they seem nervous, blush etc.

During a discussion they do not express their feelings nor reveal their opinion easily. Also they are easily hurt by criticism that is why they often avoid saying publicly what they think.

DR Lynn Wright argues that all these occur due to the differences between the parts of the brain of left- and right-handers. “Left-handed people hesitate. We know that the left side of their body receives commands from the right hemisphere of the brain. This is the side that controls the negative aspects of emotion. We have examined 46 left- and 66 right-handers. The first ones gave us responses such as: I can’t stand critics, I worry about mistakes etc. It were obviously pessimistic messages.”
