Where does this blood come from? People who are healthy give some blood so that it can be used in this way. Every three months they go to a place where blood is collected. A special kind of needle is put into the arm. It does not hurt. The blood runs through the needle (针) and through a rubber tube (管) into a bottle. A pint of blood is taken away. Then the person who has given the blood drinks a cup of tea or coffee. He sits for a few minutes. Then he feels quiet well and goes away. Three months later he comes back and gives another pint.

  A person who gives blood in this way feels happy. He knows that his blood will be used to save someone’s life. Perhaps one day he himself will need blood.

  When you are older, you may decide to give blood in this way. But you can not do this until you are eighteen.
