SCIENCE
Left-handed Geniuses S
ome of the world’s most creative geniuses have been left-handed. The artists Leonardo da Vinci and Michelangelo were both left-handed, as was the scientist Isaac Newton. And from the world of music, Mozart, Beethoven, Jimi Hendrix, and Paul McCartney are among those also known as “lefties.” Why are some people left-handed and others right-handed? Medical researchers believe that people are left-handed only by chance. Studies have shown that about 1 in 10 people are left-handed. So, is there a connection between creative genius and left-handedness? In my opinion, there is at least one clear connection. Left-handers encounter many difficulties in their daily lives. Most machines and tools, such as scissors or computers, are designed for right-handers. As a left-handed person myself, I feel that “lefties” have to struggle to do normal things that right-handed people find quite easy. I’m convinced that learning to overcome these problems makes us work harder—and being able to work hard is an important part of becoming successful.
