A Call From My Aunt

My old Aunt Mira called me today. She told me 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?", I asked her.
"Naturally", she replied, "I sit in the bathroom for a half-hour in the morning and again at night."
"No", I said, "I mean do you take anything?"
"Naturally", she answered, "I take a book."
