655 Why Are Some People Left-Handed?

Left-handedness — sometimes called “sinistrality” — means you prefer to use your left hand rather than your right hand for routine activities, such as writing. Most people who have studied left-handedness believe that approximately 10 percent of the people in the world are left-handed.

Experts believe this percentage has remained fairly consistent throughout time. Historically, the left side and left-handedness have been considered a negative thing by many cultures.

For example, the Latin word sinistra originally meant “left” but eventually took on the connotations of “evil” or “unlucky.” This connotation lives on today in the form of the English word “sinister.”
