Being Left-handed ina Right-handed World

   The world is designed for right-handed people,but why does a tenth of the population prefer the left?   71 

   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.

  72   In fact, identical twins, whoshare the same genes, can sometimes prefer to use different hands. There arealso 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 andleft-handedness have been considered a negative thing by many cultures.   73   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 thehand of judgement. Various activities and experiences become rude or even signsof bad luck when the left hand becomes involved. In some parts ofScotland, it isconsidered bad luck to meet a left-handed person at the start of a journey.   74   A person giving directions will put their left handbehind them and even physically try to point with their right hand ifnecessary. In some Asian countries, eating with the left hand is consideredimpolite.

 75   Peoplecome to realize that left-handedness is natural. People even noticed that manyfamous people are left-handed, including Benjamin Franklin, Leonardo Da Vinci,and Charlie Chaplin. Some researchers find out that lefties are more creativeand can deal with abstract thinking better. The left-handedness is more easilyadaptable to the right-handed world as well. Being left-handed is no longer asad story now; instead, it is a wonderful gift or maybe it is something youshould take pride in.
