       Do you use your right hands more or left hands more? Very few of us use both of our hands well.

Most people use right hands. Only about five people of a hundred use left hands. New-born babies can

take things with either of their hands, but in about two years, they like to use their right hands. Scientists

don't know why this happens. They've stunted it. They think our animal ancestors used their right hands,

this may not be true. Monkeys are our closest relations in the animal world. Scientists have found that

monkeys like to use one of their hands more than the other------but it can be either hand. There are as

many right-handed monkeys as the left-handed ones. Next time you visit the zoo and watch the monkeys

carefully. You'll see that some of them will use their right hands and others will use their left hands. But

men use their right hands better and this makes life difficult for the left-handed ones. We live in a

right-handed world.

       Some scientists have found out that more of successful people are left-handed, but they don't know

why. But they are working hard to discover the secret.
