reports about the eventual fatalities due to radiation leak back there where they are stationed." Baxter looked back at me steadily. "There are a lot of rumors about the high mortality rate among Accident Prones in space, too." He was right. We had started the rumors. We wanted the Prones alert, active and scheming to stay alive. More beneficial accidents that way. Actually, most Prones died of old age in space, which is more than could be said of them on Earth, where they didn't have the kind of protection the Service gives them.
