Read the following article and answer the question. Article: One of the easiest and cheapest ways to help your health is just to sleep eight hours or more every night, but more and more people in the world are not sleeping enough.

The more hours you don't sleep, the more hours you should sleep to "pay back" the hours on your "sleep credit card". For example, if you sleep four hours on Monday and then sleep eight hours on Tuesday, on Wednesday you will still have a "sleep deficit" of four hours. This deficit can continue for months or even years. People with a "sleep deficit" are sleep-deprived. Driving and making decisions can be dangerous for these people. Another research shows people should sleep nine or ten hours every night. More than half the people in the world may be running a "sleep deficit". You didn't do your homework last night?

Some doctors write clearly , but most doctors do not. Chemists have more chances to read doctors' notes, but sometimes doctors write so badly that even the chemist can't read them.

Her husband thought a moment, then he had an idea. "Thank you," said his wife. "That's a very good idea." She went to the chemist's shop and gave the doctor's note to the chemist. The chemist looked at it very carefully. Then he said politely, "Could you wait a moment, madam?" He went to the back of the shop. After a few minutes he returned carrying a large bottle.
