Old Aunt Dora went to her doctor to see what could be done about her 
constipation.
"It's terrible," she said, "I haven't moved my bowels in a week."
"I see. Have you done anything about it?" asked the doctor.
"Naturally," she replied, "I sit in the bathroom for a half- hour
in the morning and again at night."
"No," the doctor said, "I mean do you take anything?"
"Naturally," she answered, "I take a book."
