     What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed. Today about 15%

of people are left-handed. But, why are people left-handed? The answer is the way the brain (脑子) works.

The brain has two halves-the right half and the left half. The right half controls (控制) 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 the brain are about the same size. But each side controls different things. The left side

controls language, maths and logic (逻辑). 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, colour 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.
