After a while he decided to visit the doctor. “ I just can’t go to sleep at night. What should I do?”
“ I have a suggestion,” said the doctor. “ Try counting numbers. By the time you reach one thousand, you’ll be asleep, I’m sure of it.”
The next day the man returned to the doctor’s office. “ Well,” said the doctor “ How are you today? Did you try my suggestion?”
