that Seniors do most of the work and the Diagnostician-in-Charge gets most of the credit, or all of the discredit if things go wrong. And speaking of cases which might not go well, I would like to discuss your plans for the birth of your Unborn. The endocrinology of its parent and Protector is quite complex, and I am most interested in this one. However, I can foresee a few purely physical problems which …”
Conway nearly choked at the understatement, and it was a moment before he was able to speak.
“Must all verbal communication cease while it is eating?” said Thornnastor impatiently, using the mouth closest to Murchison. “Why wasn’t your species foresighted enough to evolve at least one additional orifice for the ingestion of food?”
“Pardon me,” Conway said, smiling. “I would be delighted to have any assistance and advice you can give me. The Protectors of the Unborn are the most untreatable life-form we’ve encountered, and I don’t think we have discovered all the problems yet, much less found solutions to them. In fact, I would be most grateful if your commitments would allow you to be present during the birth.”
“I thought you’d never ask, Conway,” Thornnastor rumbled.
“There are several problems,” Conway said, rubbing his middle gently and wondering if one of them was going to be an attack of indigestion through eating his food too quickly. Apologetically, he went on. “But right now my mind is still sensitized to the Hudlar material and the questions which have arisen as a result of my recent experiences in the Hudlar OR and Geriatric wards. The questions are psychological as well as physiological, and so insistent that I find it very difficult to clear my mind for consideration of the Protector case. This is ridiculous!”
“But understandable, considering your recent total involvement with FROB life-forms,” Thornnastor said. “But if you have unresolved problems regarding these Hudlars, the simplest way of clearing your mind of this troublesome material is to ask the questions at once and obtain as many answers as possible, even though they may be unsatisfactory or incomplete answers, so that you will have taken the matter as far as it is possible to go with it at the present time. Your mind will accept this and allow you to think of other things, including your perpetually pregnant Protector.
“Your particular mental quirk is far from rare, Conway,” the Tralthan went on, slipping into its lecturing voice. “There must be a very good reason why your mind doesn’t want to leave the subject. Perhaps it is close to drawing significant conclusions, and if the question is shelved now the pertinent data might fade and be lost. I realize that I am beginning to sound like a psychologist, but one cannot practice medicine without acquiring some knowledge in that field. I can, of course, help you with the physiological questions on the Hudlar life-form, but I suspect that it is the psychological aspect which is crucial. In which case you should consult the Chief Psychologist without delay.”
“You mean,” Conway said faintly, “call O’Mara right now?”
“Theoretically,” the Tralthan replied, “a Diagnostician may request the assistance of any member of the hospital staff at any time, and vice versa.”
Conway looked at Murchison, who smiled sympathetically and said, “Call him. On the intercom he can only indulge in verbal violence.”
“That,” Conway said as he reached for the communicator, “doesn’t reassure me at all.”
A few seconds later the scowling features of the Chief Psychologist filled the tiny screen, making it impossible to tell how or if he was fully dressed. O’Mara said coldly, “I can tell from the background noise and the fact that you are still masticating that you are calling from the main dining hall. I would point out that I am in the middle of my rest period. I do rest occasionally, you know, just to fool you people into thinking that I’m only human. Presumably there is a good reason for your making this call, or are you complaining about the food?”
Conway opened his mouth, but the combination of facing an angry O’Mara and a mind which was still too busily engaged in formulating his questions kept any words from coming out.
“Conway,” O’Mara said with exaggerated patience, “what the blazes do you want?”
“Information,” he replied angrily. Then he softened his tone and went on. “I need information which might help in the Hudlar geriatric work. Diagnostician Thornnastor, Pathologist Murchison, and I are presently in consultation regarding …
“Which means,” O’Mara said sourly, “that you’ve dreamed up some harebrained scheme over lunch.”
… A proposed method of treating their condition,” Conway went on. “Regrettably, little can be done for the present occupants of the ward, since the degenerative condition is too far advanced in them. But early preventive treatment might be possible provided my idea has physiological and psychological support. Thornnastor and Murchison can give me detailed information on the former, but the key to their treatment, and any hope of its ultimate success, depends on the behavior under stress, adaptive ability, and potential for reeducation in aged but pregeriatric FROBs. I have not yet discussed the clinical problems which would be encountered, because to do so would be a waste of time if the answers you give me preclude further investigation.”
“Go on,” O’Mara said, no longer sounding half-asleep.
Conway hesitated, thinking that his period of intensive Hudlar surgery, the visits to the FROB geriatric and infant wards, some old memories from his early childhood, and possibly material from his other-species mind partners had all contributed to an idea which was very likely unworkable, ethically questionable, and so ridiculous that O’Mara might well have second thoughts regarding his suitability as a future Diagnostician. But it was too late now to hold back.
“From my FROB tape and lectures at various times on Hudlar pathology,” he went on, nodding in acknowledgment toward Thornnastor, “it is clear that the various painful and incurable conditions to which the aged of that species are prey are traceable to a common cause. The loss of function in the limbs and the abnormal degree of calcification and fissuring at the extremities can be ascribed to the simple deterioration in circulation which is common to the aged of any species.
“This is not a new idea,” Conway said, glancing quickly toward Thornnastor and Murchison. “However, as a result of working on a large number of Hudlar limb and organ replacement operations from the Menelden accident, it occurred to me that the deterioration I observed in the organs of absorption and evacuation among the aged FROBs was very similar to the temporary condition which occurred during the replacement of a heart, although at the time I was too busy to note the signs consciously. In short, the problems of the FROB geriatrics are due to circulatory impairment or madequacy.
“If the idea isn’t new,” O’Mara said with a flash of his characteristic sarcasm, “why am I listening to it?”
Murchison was watching him in silence. Thornnastor continued to watch its food, Murchison, O’Mara, and Conway, also without speaking.
“The Hudlars are a very energy-hungry species,” Conway went on. “They have an extremely high metabolic rate which requires a virtually continuous supply of nutrient via their organs of absorption. The food thus metabolized serves the major organs, such as the two hearts, the absorption organs themselves, the womb when the entity is in gravid female mode, and, of course, the limbs.
“I had learned from the pathology lectures,” he continued, “that these six immensely strong limbs are the most energy-hungry system of the body, and demand close to eighty percent of the nutrient metabolized. But it was not until the recent Hudlar experience that my mind was drawn forcibly to this data, and to the fact which is also widely recognized, that it is the ultrahigh metabolic rate and excessive food requirement which enables the adult Hudlar to be so fantastically resistant to injury and disease.”
O’Mara was getting ready to interrupt again, and Conway went on quickly. “With the onset of old age their troubles invariably begin in the limbs, which demand an even greater proportion of the body’s available resources to fight it. This places increasing stress on the twin hearts, absorption, and evacuation organs, all of which require their share of and are interdependent on the circulatory system’s nutrient content. As a result these systems go into partial failure, which further reduces the blood supply to the limbs, and the body as a whole slides into a degenerative spiral.”
“Conway,” O’Mara said firmly, “I assume this lengthy but no doubt oversimplified clinical picture is for the benefit of the poor, ignorant psychologist so that he will understand the psychological questions when they come, if they ever come.
Continuing with its meal, Thornnastor said, “The clinical picture is oversimplified, I agree, but essentially correct, although your method of describing it suggests a new approach to the problem. I, too, am impatient to know what it is that you intend.”
Conway took a deep breath and said, “Very well. It seems to me that the drain on the age-reduced resources of these Hudlars, represented by the irreversible limb conditions, can be alleviated before onset. With reduced
