    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 knows that. Yet many people do not seem to know that

memory works in the same way. When someone says that he has a good memory, he really means that he

keeps using his memory. When someone else says that his memory is poor, he really means that he does not

give it enough chance to become strong. 

    Have you ever found that some people can't read or write but they have better memories? This is because

they cannot read or write and they have to remember things; they cannot write them down in a little notebook.

They have to remember days, names, songs and stories; so they are using their memory all the time. 

    So if you want to have a good memory, learn from the people:practise remembering.
