Being Left-handed in a Right-handed World

The world is designed for right-handed people, but why does a tenth of the population prefer the left? 1.

The answer to it remains a bit of a mystery. Since scientists have noticed that left-handedness tends to run in families, it’s assumed that left-handedness has a genetic(基因的) component to it. 2. In fact, identical twins, who share the same genes, can sometimes prefer to use different hands. There are also plenty of theories on what else might determine which hand you write with, but many experts believe that it’s kind of random.

Historically, the left side and left-handedness have been considered a negative thing by many cultures. 3. In some areas, the left hand became known as the “unclean” hand. In many religions, the right hand of God is the favored hand. For example, Jesus sits at God’s right side. God’s left hand, however, is the hand of judgement. Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved. In some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a journey. 4.A person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary. In some Asian countries, eating with the left hand is considered impolite.

5.People come to realize that left-handedness is natural. People even noticed that many famous people are left-handed, including Benjamin Franklin, Leonardo Da Vinci, and Charlie Chaplin. Some researchers find out that lefties are more creative and can deal with abstract thinking better. The left-handedness is more easily adaptable to the right-handed world as well.
