 How would the shot theoretically cure headaches?
Why, having a head, of course! But Macklin is exactly what we need for a quick, dramatic test. Who would have financed a study of cyclic periods of the hedgehog? "When we prove our results that should be of enough practical value for anyone. No one knew whether his Theory of Spatium was correct or not because no one had yet been able to frame an argument with it. 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. For the past seven years Macklin—who was the Advanced Studies Department of Firestone University—had been involved in devising a faster-than-light drive to help the Army reach Pluto and eventually the nearer stars. If so, it was a case of Ad astra per aspirin . Despite his impressive body, some years before he had suffered a mild stroke ... or at least a vascular spasm of a cerebral artery. It was known that he suffered from the vilest variety of migraine. "Doctor, we understand you have severe headaches," Mitchell said. "That's right, Steven. Migraine." "I would have said the common cold," Macklin replied, "but I suppose from what you have said you mean headaches." "Everybody has them at some time in his life. "But think," Ferris interjected, "what a boon it would be if everyone could be cured of headaches forever by one simple injection." "I don't suppose the manufacturers of aspirin would like you. "Aspirins would still be used to reduce fever and relieve muscular pains," Mitchell said. "There are a number of different causes for headaches—nervous strain, fatigue, physical diseases from kidney complaints to tumors, over-indulgence—but there is one effect of all of this, the one real cause of headaches," Mitchell announced. "The pressure effect caused by pituitrin in the brain," Mitchell said eagerly. "That is, the constriction of blood vessels in the telencephalon section of the frontal lobes. It's caused by an over-production of the pituitary gland. "In certain areas it is valuable to have a constriction of blood vessels." "The virus," Ferris explained, "can easily be localized and stabilized. A colony of virus in the brain cells will relax the cerebral vessels—and only the cerebral vessels—so that the cerebrospinal fluid doesn't create pressure in the cavities of the brain."
 It would address the root problem of every headache. By focusing on the core behind a headache, it can be used in any circumstance.
 It would address the root problem of every headache. By focusing on the core behind a headache, it can be used in any circumstance.  It would separately address any problem that could cause a headache, from tumors to fatigue. It's built to be an answer to everything.  It constricts the blood vessels with an artificial virus.  It's not a cure at all, it's a virus.
