This Sunday the 13th, International Left-Handed Day is celebrated. With this party, the people who write and use the left side of the world try to raise public awareness to reduce the difficulties they face.
Although no one has arrived at a definitive reason why some people are left-handed, about 10% of the world’s population is, and it is believed to be genetic. This day was established in 1976 by Dean R. Campbell, founder of the ‘Left-Handers Club’.
Next, learn about some curiosities of this segment of the population considered “special” for science.
1. The brain “cross-controls your body”
The reason why a person is left-handed is the brain, which determines which side of the body is dominant in an individual.
Divided into two hemispheres, the brain controls the body in a “cross” way, that is, the left hemisphere controls the right side of the body and vice versa, so in the case of lefties, the right side of their brain is the predominant.
2. ¿Genetics?
Although there is no known definitive reason why some people write left-handed, it is thought that genes are very present when it comes to being left-handed and it is very likely that if a person is left-handed, their children will be too.
3. Persecuted by the inquisition
Being left-handed hasn’t always been “best”. People who write with the left have historically been persecuted. A clear example was that of the Inquisition, which persecuted, condemned, and burned many left-handed people alive for considering them “servants of Satan.”
4. Zulu celebrities
Many celebrities and personalities in the world have been and are zudas.
Scientists like Marie Curie, Isaac Newton, Albert Einstein or Alan Turing were left-handed; astronauts Neil Armstrong and Buzz Aldrin; artists like Van Gogh, Leonardo da Vinci or Beethoven; musicians Jimi Hendrix, Paul McCartney, David Bowie, Kurt Cobain and Bob Dylan; soccer star Maradona and tennis player Rafael Nadal, and historical figures such as Adolf Hitler, Marilyn Monroe and Charles Chaplin.
5. They have a town
A town in the United States is called ‘Left hand’ (left hand). It is located in the state of West Virginia. Its population in 2009 did not exceed 400 inhabitants.
6. An exclusive store
The most famous left-handed store in the world is called Anything Left-Handed and is located in London, UK. It was created in 1968, a pioneer in its genre.
Until 2006, it was at 53 Bewer Street, in the center of the British capital. Now he only sells online.
7. Diseases
Research published in the journal ‘Neuropsychologia’ revealed that left-handers are at greater risk of having certain mental health problems, such as attention deficit hyperactivity disorder (ADHD), dyslexia and even schizophrenia.
“Proof of this would be that while left-handers represent only 10% of the population, 20% of schizophrenics are left-handed,” according to the study.
8. Left-wing phobia
Sinistrophobia is defined as a persistent, abnormal, and unjustified fear of things located to the left, of picking things up with the left hand, or of being left-handed.
Those who suffer from it consider the left a bad omen. The superstitions that condemn it have penetrated deeply into these people, to the point of producing a lot of anxiety and even panic attacks in serious cases.
