remarkable phenomena: a soothing drug and its antidote, both of 100% efficiency. A new solution now presented itself—a solution whose details were simple and obvious. Give the drug to children. Let them live in a carefree paradise of unworry until the age of seventeen—at which time, apply the four-year withdrawal treatment. At twenty-one, they were ready to step into the adult world, unmarked by the horrors of childhood and equipped to face maturity with a calm, if somewhat blank mind. At the age of seventeen, then, a choice: forward or backward. One out of every ten elected to remain in the synthetic dream-world forever, thereby removing themselves from a world in which they probably would not have been fit to contend. It was an efficient screening process, eliminating those dreamers who would not have withstood the grind, who would have retreated from reality anyway, would have slipped into neurotic fancies.

The third capsule was the one most frequently chosen. It was a delayer; its effect, neither positive nor negative, was to allow its taker's hormones to remain suspended during the period of choice. "I've got three days, don't I, Dad?" The terms of the situation, implanted in each child's mind long before he could possibly understand the meanings of the words, now stood out sharply in Larry's mind. Larry's father nodded. "You took the green one?" "Yes. Was that wrong?" "It's what I did when I was your age," the older man said. "It's the only sensible thing to do. Yes, you have three days to make up your mind. You can go on taking the unworry capsules for the rest of your life—or you can begin withdrawing. You'll have to decide that for yourself." Something fluttery throbbed in the pit of Larry's stomach. It was the first sign of worry, the first agony of decision-making. He remained calm; despite his lifelong use of Koletsky's drug, its peculiar properties were such that he felt no need of it now. Yet—how did he choose? In three days, how? Uneasily, he wiggled his feet against the cool, yielding surface of the floor for a moment, left the bed, crossed the room, threw open the door. Across the hall, the robonurse was ministering to his younger
