How much sleep do we need? We are all different. Some people need only three hours of sleep a night. Others need ten hours of sleep a night. Most Americans sleep an average (平均) of seven to eight hours a night. After the age of fifty, the average sleep time goes down to 6.5 hours a day. Most people have a night when they can not sleep. About one in three Americans has a problem with sleep. Many of these people can not fall asleep. The name of this problem is insomnia.
This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make them sleep. Benjamin Franklin, a famous statesman and inventor, had four beds. He moved from one to another to fall asleep. King Louis XIV of France had 413 beds and hoped to fall asleep in one of them. Mark Twain, a famous American writer, had a different way. He lay at the other the end of the bed!
