A patient goes for an appointment with his cardiologist.

Doctor, “I hear you, what’s wrong with you?”

Patient, “I have trouble with one of prescribed medications.”

Doctor, “What’s the problem?”

Patient, “You told me to put on a new patch every four hours and now there is no place to put a new one!”

Doctor, “Let me see, take off your shirt please. You haven’t removed old patches?!

Patient, “Why should I?”
