Spaceship crews should be selected on the basis of their non-irritating qualities as individuals. No chronic complainers, no hypochondriacs, no bugs on cleanliness—particularly no one-man parties. I speak from bitter experience. Because on the first expedition to Mars, Hugh Allenby damned near drove us nuts with his puns.
