Question

What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed. Today about 15% of the people are 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 and the left half. The right half controls (控制) the left side of the body, and the left half controls the right side of the body. So right-handed people have a strong left brain, and the 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, Math 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 color and music. It is also good at recognizing (认出) faces. This does not mean that all artists are left-handed and all accountants (会计师) are right-handed. Some right-handers have a strong right brain, and some left-handers have a strong left brain.
