"Yes, sir."

"It shows here that you first underwent replacive surgery in 1991. Correct?"

"Yes."

"Remember what it was for?"

"Yes, I had heart trouble. They fixed me up with one of those big jobs requiring my carrying batteries under my armpit."

"One of those early models. And this shows that at various times since then you have undergone replacive surgery some eighty-seven times, including three replacements of a pulmonary nature."

Again Lee hesitated. The number of times he had had a worn organ or tissue repaired or replaced was more than a little hazy. After the novelty of the first few times when he found himself with a new stomach, or liver, or muscle, he had started to take these things as a matter of course. He gave a little nervous laugh. "If that paper says so, I suppose so, doctor."

"Yes. Well, everything seems to be functioning properly now, doesn't it? With the exception of your head, of course."

"Yes, yes I feel fine otherwise." Lee was feeling uncomfortable. "Doctor, could you tell me what this is all about? I must have answered these questions half a dozen times before to those other people."

"In just a moment. First I need to know you a little better. Your medical history lists your occupation as 'cabinet maker'."
