The club says it is now 17 years old, the day has been celebrated with right and left sports matches, left-handed drinking events and other activities.
It is based on the Latin word “sinistra”, meaning “to the left”. But over time, it began to accumulate a connection with the evil that still exists today.
Throughout the ages, left-handedness has been associated with weakness, impurity, or evil. Nowadays, few people consider the left-handers among us evil, but they endure the numerous inconveniences of a right-handed world.
Only the pros
About 10% of the world’s population is left-handed, researchers say, although this number varies with time and place. In more liberal times and cultures, left-handedness was more common, while at more limited times and places, the incidence seemed to decrease, the researchers said.
In a 1996 study, Harvard Medical School researchers found that orthopedic surgeons, librarians and mathematicians are predominantly right-handed while lawyers and architects are a group of “least right-handed or least left-handed.” Other studies have shown that there are more left-handed people working as artists and musicians and in university settings. Interestingly, more than 20% of Apollo astronauts are left-handed, according to NASA.
Outside of politics, at least four of the previous seven presidents were left-handed: Barack Obama, Bill Clinton, George HW Bush, and Gerald Ford.
Ronald Reagan also appeared regularly on left-handed lists even though he wrote with his right hand. Some historians claim that he was born left-handed but was forced to convert when he was a child.
Why are so many US presidents left-handed?
There’s no clear research, and it might just be a stroke of luck.
But the leftrightwrong.com website offers a few theories: Politicians are often lawyers, a profession with the highest concentration of left-handed people; leftists are mentally resilient for all the tribulations they endure in a right-handed world; left-handed people with well-known language processing on both sides of their brain.
Income from legitimate
Research shows that left-handed people can have an increased incidence of high blood pressure, irritable bowel syndrome, schizophrenia, and even premature death. According to 2014 research, they can also get short-term results when it comes to income.
Economist Joshua Goodman of the Kennedy School of Government at Harvard University found that left-handed income is 10% to 12% lower than that of right-handed people.
That is in stark contrast to a 2006 article by the National Bureau of Economic Research, in which economists from Lafayette and Johns Hopkins University found that “among men who had a degree those who report left-handed earn 15% more than those who report as right-handed. “
This is also not true for left-handed women, they say.
