Most people around the world are right-handed.This fact also seems to have held true throughout history.In 1977 scientists studied works of art made at various times in history.Most of the people shown in these works of art are right handed，so scientists guessed that right-handedness has always been common.But what do Leonardo da Vinci，Marie Curie，and Albert Einstein have in common？They were all left-handed along with other famous people including Brad Pitt Prince William，and Barack Obama.In fact，an estimated 13 percent of the world's population may be left-handed.
Many researchers claim to have found relationships between left-handedness and various physical and mental characteristics，such as blond hair，blue eyes，and sleep difficulties.Other studies have found a higher-than-normal level of left-handed people in certain occupations（职业），including professional baseball players，architects，as well as prisoners.However，some of these connections are very weak，and others have not been proven.
What makes a person become right-handed rather than left-handed？One simple idea suggests that people normally get right-handedness from their parents.Studies have found that two right-handed parents have only a 9.5-percent chance of having a left-handed child，while two left-handed parents have a 26-percent chance of having a left-handed child.Another common theory is that left-handed people suffer mild brain damage during birth，which makes them left-handed.
Whatever the reasons behind it，people's attitudes toward left-handedness have changed a lot over the years.Statistics show that although 13 percent of young people are left-handed，only six percent of the elderly are jye.ai-handed.Left-handed children used to be punished until they began using their right hand like other children，but today people who are left-handed are no longer looked down on nor are they considered abnormal For most people today，either case is perfectly acceptable.There are even a number of shops now selling products for left-handed people，such as left-handed can openers，guitars，and even a left-handed camera.发布：2024/10/26 21:0:2组卷：7引用：3难度：0.3673．When first
