        Which hand do you use to write, hold chopsticks or shakehands? Most people use their right hand. Studies show that aboutone out of ten people in the world uses the left hand. Left-handersare much less common.
        No one is sure what makes a person right-handed or lefthanded. Some people think that left-handed parents will oftenhave left-handed children, but that is not true. Kids usually showwhich hand they use more often at an early age.
        Long ago, the Romans believed that the right side of thebody was the good side, and the left side held evil spirits.Because of the myth, parents forced their left-handed children touse the “right” hand instead of the wrong dirty hand.
        Now, most people don’t really mind being left-handed.However, left-handers still find it hard to use many things. Mostcan openers, rulers, guitars are easier for right-handers to use.To make life more convenient for left-handers, there aremore things and tools designed just for them. Now left-handersdo not need to be “left out.”
