 Why has Infield attached a lightning rod to his head?
Henry Infield placed the insulated circlet on his head gently. The gleaming rod extended above his head about a foot, the wires from it leading down into his collar, along his spine and finally out his pants leg to a short metallic strap that dragged on the floor. The people we treat are on one side of the line and we're on the other. "I dunno, Henry, but staying on our side is a pretty good way to keep sane One cannibal walking another with sleeping sickness doesn't cure anything. His mind went back to the first gyro ball he had ever issued; the remembrance of his pride in the thing sickened him. Floating before him in memory was the vertical hoop and the horizontal hoop, both of shining steel-impervium alloy. The gyro actually passed over a man's shoulder, through his legs, under his arms. Any time he felt the walls creeping in to crush him, he could withdraw his head and limbs into the circle and feel safe. The foetic gyro ball was worn day and night, for life. "That's just one thing, the gyro ball. "You know, Henry, not all of our Cures are so—so—not all are like that. If anybody does see that button in a patient's ear, it looks like a hearing aid. Or suppose he's walking down a railroad track and hears a train whistle—if he can hear anything over that verbal pablum gushing in his ear." But what about the severe case where we have to burn a three-dimensional smiling mother-image on the eyes of the patient with radiation? With that image over everything he sees and with that insidious voice drumming in his head night and day, do you mean to say that man's senses will only be impaired 23 per cent? Why, he'll turn violently schizophrenic sooner or later—and you know it. Infield stepped into the main stream of human traffic and tried to adjust to the second change in the air. He walked along, buffeted by the crowd, carried along in this direction, shoved back in that direction. Many "Cures" were not readily apparent. A young man with black glasses and a radar headset (a photophobe) was unable to keep from being pushed against Infield. He sounded out the lightning rod, his face changing when he realized it must be some kind of Cure. It was the first time in years that anyone had apologized to Infield for anything. Suddenly something else was pushing against Infield, forcing the air from his lungs.
