Somehow, thinking had grown difficult in the mornings recently. enough to look them up. Plenty of time! Thirty years was a long time, when he stopped to think of it. of aging. I’m afraid the treatment didn’t take fully. It might have “I guess I’m getting old, Amanda.” She smiled dutifully at the time-worn joke, but he knew she wasn’t fooled. She’d cycled to was more important. It hadn’t been a joke about his growing old, after all. But now, in a few days, He resented every second of it. It was as if the almost forgotten specter of age stood beside him, counting the seconds. But at last they were through and he was led into the quiet rejuvenation room, months of mental training, followed by crude mechanical and drug hypnosis for other months. Somewhere in every human brain lay the memory of what his cells at Research. For eighty years now, they’d been sending out the little ships that vanished at greater than the the first hope they’d found that the century-long trips between stars in the ponderous shuttles within minutes, even—but finding the mechanism in the brain taken even longer. Now they did it with dozens of mechanical aids in addition to the hypnotic instructions—and did it usually in a single sitting, with the full transformation of the body taking less than a week after the treatment! But with all the equipment, it could relax so easily.... He came out of it without even a headache, while they were fatigue on the operator’s face told him it had been a long and difficult job.

The discovery that men could live practically forever had put an end to most family ties sentiment wore thin in half a century—which wasn’t much time now, though it had once seemed long enough. Strange how the years seemed to get shorter as their number increased. There’d been a song once—something about the years new thinking. There was a measure dwindling down. He groped for the lines and couldn’t remember. awake most of the night again, trying to recall them. The outside line buzzed musically, through the meal, listening to the conversation about him only when it was necessary because patience was still foreign to him. He gave it up and went to bed—to Harry had been a complete nuisance, running around with various nostrums, giving him no peace. Constant questions about can send a message on the shuttle, begging for their secret in a couple of hundred years! While a hundred other worlds make a thousand major discoveries they world no real progress had been made in two centuries the young their first fifty years of education were finished, and the older men were too conservative for really the years helped to add to the of truth in it, unfortunately. “They’ll slow up when their populations fill,” Giles repeated his old answers. “We’re still ahead richness of living now. about the years—or was it days—dwindling interrupting the work of making the Earth fit for our longevity. We can wait. We’ll have to.” down to something or other. THE YOUNGER man stared at him with the strange puzzled days. We can have the secret of this antigravity in less than a year! We—” it about twenty years before the Procyon shuttle heard its signal. Pre-setting a course may take centuries, if we can ever master it. Even with Sirius expecting the missiles and ready to cooperate. drafted for building long enough now we can finish it in three months. We know the drive works. We know it’s fast enough to reach Procyon in two weeks. We even know life can stand the trip. The Maybe if we put in stronger signaling transmitters....” “Yeah. Maybe in two centuries long it had been. Nor why. “In the spring, a young man’s fancy,” he quoted to himself, and Or how about you? Do you really want to risk losing the rest of your life rather than waiting a couple more centuries until we know it’s safe? If you do, I’ll now. The machines were quiet—and all the doors were shut. Giles shook his head, interrupting Then the engineer shut his mouth slowly. The belligerence ran out of him. He looked sick, for he had no chance for near eternity against such a relatively short those who knew their days were numbered, anyhow. “Forget it, Bill,” Giles advised. “It may take longer, but eventually we’ll find a way. With time enough, we’re bound to. And to simplify it, no memory is perfect—even cellular memory. It plan for short-term benefits. Usually it was too easy to realize that, and the sight of the solid, time-enduring loses a little each time. And the effect is cumulative. It’s like an They had to plan and build for it. They couldn’t risk that know. But you aren’t the first and you won’t be the last, if that’s any consolation. We’ve got a longer time scale than we used to have—but it’s in centuries, not in eons. For everybody, not just you.” It was no consolation. Giles nodded mechanically. “I won’t talk, of course. How—how long?” Cobb spread his hands unhappily. “Thirty years, maybe. But we can make them better. Geriatric knowledge is still on record. “And then....” Giles couldn’t pronounce the words. He’d grown old and he’d grow older. And eventually he’d die! An immortal man had suddenly found death hovering on his trail.

Those wouldn’t matter much now. For a man who had thought of living almost forever, thirty years was too short a time to count. He was passing near the club and started to slow. Then he and he drove on. What else was there for him? There, at least, he could still fill his time with work—work that might even be useful.

Now he’d taken to walking, as so many others had, for spend the long future as a cripple. “I’ll wait for you, sir,” Dubbins ties melted away too fast for interstellar while the years dwindled down— Then abruptly the line finished itself. “The years dwindle down to a precious few....” he remembered. “A precious few.” Those dwindling years had been precious once. He unexpectedly that was forbidden. The years seemed precious to the old man then.
