On the 13th of August, left-handed people 'recovered', their day

All year round, they juggle home and office arrangements designed for the comfort of those who use their right hand as their dominant hand. They 'endure' doors, kitchens, sinks, mice, keyboards and desks that are mostly right-handed. But August 13 is the day of 'redemption' for left-handers: an international day dedicated to them, to celebrate a particularity that is no longer considered a defect to be corrected as in the past and that today affects about 10% of the world population .

As reported by an article last year in the Washington Post, in 1860 only 2% of the population preferred the use of the left hand. The percentage in 1920 has risen to 4% and then reaches 10% today.

Left-handed day was established in 1992 by the Left Handers Club in the UK and there is no shortage of specificities for left-handed people, both positively and negatively according to science. They remember events better, according to a 2001 research, because their brain hemispheres are more closely connected, they are more skilled in mathematics, in solving complex problems than in simple arithmetic, according to a 2017 study involving 2,314 Italian students. . According to another 2017 study, they also have an advantage in interactive sports, such as table tennis or baseball, which require responsiveness. They are strong in boxing.

From the point of view of health, while it is true that they have a higher risk of breast cancer, on the other hand they have an advantage, for example for post-stroke recovery. There are many famous left-handed people: from former US President Barack Obama, to Beatles bassist Paul McCartney, to Microsoft founder Bill Gates, Prince William and actress Angelina Jolie. But also Marie Curie, Albert Einstein, Leonardo Da Vinci.
