"To celebrate," Ferris said. The colonel shrugged. "That's as good a reason as any." On the street, Mitchell watched the two men go off together in bewilderment. Macklin was playing jacks. "Do you think we'll have to use force on Macklin to get him to same. Mitchell forced himself to awaken, with some initial difficulty. He lay there, blinking the sleep out of his eyes, listening to his Mitchell smiled to himself. He was in luck Macklin had answered the "I suppose so," Macklin said humbly. "You've found yourself worrying—thinking—about a lot of other "You're right. Besides who cares if you or I are cured of headaches? have time to think about." "If you say so." now Macklin—" Our reputations don't go outside our own fields," Mitchell said. "But Elliot Macklin had inherited the reputation of the late Albert Einstein in the popular mind. He was the man people thought of when the word able to frame an argument with it. Macklin was in his early fifties but looked in his late thirties, with the build of a football player. The government took up a lot of his time using him as the symbol of the Ideal Scientist to help recruit Science and Engineering Cadets. that the project was nearing completion. If so, it was a case of Ad . The only thing that could delay the project was Macklin's health. Despite his impressive body, some years before he had suffered a mild known that he suffered from the vilest variety of migraine. A cycle of the headaches had caused him to be absent from his classes for several weeks, and there were an unusual number of military uniforms seen around the campus.

"Macklin's always seemed a decent looked more than a little like a postgraduate student, and Mitchell suspected that that was his intention. He shook hands warmly with Mitchell. "Good of you to ask me over, lavish salary can't be much consolation when that ripping, tearing agony begins, can it?" their headaches." "Yes," Macklin said. "But think," Ferris interjected, "what a boon it would be if everyone could be cured of headaches forever would please about everybody else." "Aspirins would still be used to reduce fever and relieve muscular pains," Mitchell said. "How can you have a specific for a number of different causes?" Macklin virus that feeds on pituitrin." "That may mean the end of headaches, but I would think it would mean the end of the race as well," Macklin said. "In certain areas it is valuable to have a constriction of blood vessels." works, I could stop using that damned gynergen, couldn't I? The stuff makes me violently sick to my stomach. But it's better than the migraine. How should I go about removing my curse?" He reinserted the pipe. "But not on humans?" Macklin asked. "I'm tempted," Macklin said hesitantly, "but the answer is go. I mean it? You aren't much better off with it than without, are you? I've heard some say they preferred the migraine." possibilities. All Macklin held his head in both hands. "Why did you two select unverified results to the press. It's too early for that!" "Don't be so stuffy and conservative, Mitchell! Macklin's cured, isn't he? By established periodic cycle he should be suffering hell right now, shouldn't he? But thanks to our treatment he is perfectly happy, with no unfortunate side effects such as gynergen produces." will hand down a ukase demanding our virus, just as they demanded the husband for a full day. The effects of a narcotic would have worn off by this time." "Most known narcotics," she admitted, "but evidently you have discovered something new. Is it so expensive to refine you and Ferris have to recruit new customers to keep yourselves supplied?" peacefully in a corner scratching under his arms with the back of his knuckles. Jerry, their control in the experiment, who was practically Dean's twin except that he had received no injection of the E-M Virus, was stomping up and down punching his fingers through the wire, worrying the lock on the cage. "Jerry is a great deal more active than Dean," Mitchell said. dum-de-de-dum-dum-dum . As they waited Mitchell glanced at Ferris. He seemed completely undisturbed, perhaps slightly curious. "You are the gentlemen who gave Dr. Macklin the unauthorized "Why not? You can't do much worse than murder him now. That might be just as well. We have laws to cover that." The colonel led them into the comfortable, over-feminine living room. suddenly realized Macklin used a pipe as a form of masculine protest to used to be a mathematical genius." "And now?" Mitchell said impatiently. "What did he mean, Macklin is an idiot?" Mitchell asked. "Not an idiot," Colonel Carson corrected primly. "Dr. Macklin is a "I'm not so dumb," Macklin said defensively. "That's just on book learning," Macklin said. "There's a lot you learn in life that you don't get out of books, son." "What have you done to him?" the colonel asked straightforwardly. "We merely cured him of his headaches," Mitchell said. "How?" Mitchell did his best to explain the F-M Virus. "All I want to know is why Elliot Macklin has been made as simple as if virus colony overcontrols the supply of posterior pituitary extract in "Just a moment," Mitchell interrupted, "we can cure Macklin." antitoxin to combat the virus. We had always thought of it as a "What do you mean you don't like it?" Carson demanded. He added, "Sir?" "I figure you mean to put me back like I used to be." "Yes, doctor," Mitchell said eagerly, "just as you used to be." " With "No, sir!" the mathematician said. "I shall not go back to my original state. I can remember what it was like. Always worrying, worrying, worrying." what was an infinity anyway? All that sort of schoolboy things. It's peaceful this way. My head doesn't hurt. I've got a good-looking wife and all the money I need. I've got it made. Why worry?" Colonel Carson opened his mouth, then closed it. his former level of intelligence but he's legally responsible. There are millions of morons running around loose in the United States. They can get married, own property, vote, even hold office. Many of them do. You can't force him into being cured.... At least, I don't think I don't think that even previously he made too many personal decisions for himself. Perhaps she could influence him." treatment. He wants to remain in his state of lower intelligence." She nodded. "If those are his wishes, I can't go against them." "Yes. I can't go against Elliot's wishes. It would be monstrous to put him back where he would suffer the hell of those headaches once again, where he never had a moment's peace from worry and pressure. He's happy now. Like a child, but happy." Ferris' antitoxin treatment is the best method of restoring Dr. Macklin Her mouth grew petulant. "I don't care. I would rather have a live husband than a dead genius. I can take care of him this way, make him comfortable...." "I'm no psychiatrist," Mitchell said, "but I think she wants Macklin stupid. Prefers it that way. She's always dominated his personal life, and now she can dominate him completely." of her husband's genius." "Maybe," Carson said. "I don't know. I don't know what the hell to tell the Pentagon. I think I'll go out and get drunk." Mitchell glanced sharply at the little biologist. Carson squinted. "Any particular reason, doctor?"
