Question

It was Sunday afternoon and Joe C. Potato, was settling into his Barcalounger to watch the football game. He had his beer, cigarettes, and nachos within reach – life was good. Pittsburgh, his favorite team, scored a touchdown and he jumped up with a cheer, but immediately sat down as he felt a twinge of pain in his chest. “Darn angina acting up again” he said to his wife Nancy as he placed a nitroglycerine tablet under his tongue and finished his beer. Nancy sighed. “Joe, you really need to cut back on the smoking and drinking. You know the doctor said that if you don’t change your lifestyle you are going to end up having a heart attack”. “Nonsense” said Joe, “as long as I take my aspirin every day I’ll be fine.”
