About 10 percent of the population is left-handed, and there are some distinct pros and cons to left-hand dominance.
Studies suggest people who are left-handed appear to have an edge in opposition sports like tennis and fencing or certain positions on the baseball field. Lefties are also thought to have a lower risk of developing certian ailments like ulcers and arthritis.
Lefties are reportedly better in fights, which is probably because opponents don't expect a left hook.
Most operations cater to right-handed people.
Many instruments are made for righties. Legendary musician Jimi Hendrix flipped his guitar upside down so he could play left-handed.
Computer mice are traditionally made for righties and a lot of zippers are, too.
But lefties are in good company. 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.
Plus, studies show 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.
