     What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed.   

     Today, about 15% of the number of people is left-handed. But why are people left-handed? The answer

is the way the brain (大脑) works. The brain has two halves-the right half controls the left side of the

body, and the left controls the right side of the body. So right-handed people have a strong left-brain and

left-handed people have a strong right brain.   

     The two halves of he brain are about the same size. But each side controls different things. The left side

controls language, math and logical (逻辑的). When you remember new words, or when you put things in

order, you use your left side.   

     The right side of the brain controls your love of art, colors and music. It is also good at recognizing (识别)

faces.   

     This does not mean that all artists are left-handed and all accountants (会计) are right-handed. Some

right-handers have a strong right brain, and some left-handers have a strong left-brain.
