If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody kmows this, and nobody would think of questioning this fact. Yet there are many people who do not seem to know that the memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously. When someone else says that his memory is poor, he really means that he does not give it enough opportunity to become strong. The position is exactly the same as that of two people, one of whom exercises his arms and legs by playing tennis, while the other sits in a chair or a motor car all day.

If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think his parents are to blame, or that he is just unlucky, and few of us realize that it is just as much his own fault as if it was his arms and legs that were weak. Not all of us can become extremely strong or extremely clever; but all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means—practice.

Have you ever noticed that people who cannot read or write usually have better memories than those who can? Why is this? Of course, because those who cannot read or write have to remember things: they cannot write them down in a little notebook. They have to remember dates, times, and prices, names, songs and stories; so their memory is the whole time being exercised. So if you want a good memory practise remembering

1)Do all people have the same memory?

5) Why do people Who cannot read or write have better memories than those Who can?
