I don’t care for such work at zero pressure; mishap in pressure suit is too permanent—especially when somebody arranges mishap. One first thing learned about Luna, back with first shiploads of convicts, was that zero pressure was place for good manners. Bad-tempered straw boss didn’t last many shifts; had an "accident"—and top bosses learned not to pry into accidents or they met accidents, too. Attrition ran 70 percent in early years—but those who lived were nice people. Not tame, not soft, Luna is not for them. But well-behaved.
