英语翻译Today about 15 percent of the population is left-handed.But whyare people left-handed The answer is in the way the brain works.The brain has two halves-the right half and the left half .Theright half controls the left side of thebody,and the left controls the right side of the body.So right-hanged peoplehave a strong left brain,and left-handed people have a strong right brain.The two halves of the brainare about the same size.But each side controls different things.The left sidecontrols language,mathematics,and logic.When you memorize the spelling ofwords,or when you put things in order,you use your left side.The right sideof the brain controls your love of art,colour,music.It is also good at recognizing faces.This does not mean that allartists are left-handed and all accountants are right-handed.There areactually many exceptions.Some right-handers have a strong right brain,andsome left-handers have a strong left brain.
