few moments, then began to fill out a form clipped to the folder. "Well, I think you probably are due for another booster about now. There'll have to be the usual tests. Not that there's much doubt ... we like to be certain."
The middle-aged man seemed relieved. Then, on second thought, he hesitated uneasily, "Why? Is there any danger?"
Amusement flickered across the doctor's face, turned smoothly into a reassuring half-smile. "Oh, no. There's absolutely no danger involved. None at all. We have tissue-regeneration pretty well under control now. Still, I'm sure you understand that accurate records and data are very necessary to further research and progress."
Reassured, the patient thawed and became confidential, "I see. Well, I suppose it's kinda silly, but I don't much like shots. It's not that they hurt ... it's just that I guess I'm old-fashioned. I still feel kinda 'creepy' about the whole business." Slightly embarrassed, he paused and asked defensively, "Is that unusual?"
The doctor smiled openly now, "Not at all, not at all. Things have moved pretty fast in the past few years. I suppose it takes people's emotional reactions a while to catch up with developments that, logically, we accept as matter of fact."
He pushed his chair back from the desk, "Maybe it's not too hard to understand. Take 'fire' for example: Man lived in fear of fire for a good many hundred-thousand years--and rightly so, because he hadn't learned to control it. The principle's the same; First you learn to protect yourself from a thing; then control it; and, eventually, we learn to 'harness' it for a useful purpose." He gestured toward the man's cigarette, "Even so, man still instinctively fears fire--even while he uses it. In the case of tissue-regeneration, where the change took place so rapidly, in just a generation or so, that instinctive fear is even more understandable--although quite as unjustified, I assure you."
The doctor stood up, indicating that the session was ending. While his patie
