A tenth of the worlds population are left-handed. That’s 10 percent of the population. There are some distinct pros and cons to left-hand dominance.
Recent studies suggest people who are left-handed appear to have an edge in competing in sports like tennis and fencing or certain positions on the baseball field. If you’re a leftie, you are prone to have a lower risk of developing certain ailments like ulcers and arthritis.
That left hook comes in handy in a battle, as lefties are reportedly better in fights. But with some good, there’s some bad stereotypes of lefties. In some religions, the left hand is considered unclean, and in parts of Africa and India, it’s rude to eat with the left hand.
Most operations cater to right-handed people. Computer mice are traditionally made for righties and a lot of zippers are, too. Many instruments are made for righties. Legendary musician Jimi Hendrix flipped his guitar upside down so he could play left-handed.
But lefties are in good company as former President Barack Obama is one of the many left-handed public figures. Lady Gaga and Oprah Winfrey have also signed fan photos with their left hand.
I was reading additional studies on the lefty topic and it shows that some animals tend to be left-hand dominant. Researchers found kangaroos favor their left hands, and certain species of parrots eat and perform everyday functions with their left feet.
