Celebrate International Left-Handers Day on August 13!
International Left-Handers Day is August 13! To celebrate, here are some fun facts and folklore about being left-handed. Right on, left-handers!
Years ago, some teachers insisted that all students, including left-handers, learn to write with their right hand. Teachers thought that students would have an easier time if they were not "different" from right-handed writers. Some thought that using the left hand was just a bad habit. Some even slapped or punished left-handed kids who had trouble!
Now we know that everyone should use whichever hand is most comfortable. Today, 10 to 12 percent of the world's population is left-handed. It's not surprising that lefties sometimes feel "left out." Plenty of superstitions and odd terms regarding left-handedness exist.
Left-Hander Superstitions and Terms
- Many people believe that the devil is left-handed.
- The Latin word for left, sinister, also means unlucky, evil, and suspicious.
- The French word for left, gauche, also means clumsy.
- A left-handed compliment is an insult.
- A left-handed baseball pitcher is called a southpaw. (And no, there's no such thing as a northpaw!)
Why are some people left-handed and others right-handed?
Scientists aren't sure what causes left-handedness. Genetics plays a role, but it's not the whole story. For example, identical twins have the same DNA, but it is common for one twin to be right-handed and the other to be left-handed.
Many left-handers have a symmetrical brain, meaning that the left and right portions of their brain are shaped alike. Right-handers often have an asymmetrical brain: The left cerebral hemisphere is often larger than the right cerebral hemisphere.
No matter the shape of your brain, or the hand you favor, here's what we have—um—left:
Left-Handed Facts and Trivia
The Left Test
There's no sure way to measure "handedness." One of the most widely-used tests is called the Edinburgh Handedness Inventory (developed in Edinburgh, Scotland in the 1970s). This test asks participants which hand they most often use for a series of activities, including writing, eating, drawing, throwing, cutting with scissors, brushing teeth, and unscrewing a lid.
Left-handed Burgers? Baloney!
A full-page ad in USA Today in 1998 claimed that Burger King had developed the "left-handed whopper." The burger had the same fixings, but they were turned 180 degrees so that they wouldn't drip out on left-handed customers. It was a joke! The ad ran on April 1 (April Fools' Day).
August 13 is International Left-Handers Day! The tradition was started by the Left-Handers Club, a group in the United Kingdom. Club members around the world give interviews and play left-handed games.
Lefties might want to travel to Left Hand, West Virginia, where there is a church, a school, and a post office. The village was so named because it sits on the left-hand fork of the Big Sandy River, not because of the way its citizens write.
A few left-handers attending Juniata College in Pennsylvania have benefited from a scholarship just for left-handers established in 1979 by Mary and Frederick Beckley, two left-handers who met when they attended tennis class together in 1919.
If you're right-handed, try writing with your left. If you're left-handed, try brushing your teeth with your right. You're likely to find these activities surprisingly difficult.
So, tell us below if you are a lefty or righty and what you've observed about this phenomenon called handedness!
