Nerves

This story was revised slightly in 1976 with the author's note for this revision saying “In planning a sixth printing, the publisher has kindly permitted me to go over it again. A third of a century has passed since I first wrote the story, and I can look at it far more objectively. So again I've revised it slightly, eliminating inconsistencies, expanding a bit for clarity, - but essentially leaving the story as it was always meant to be.” (source the Historical Note appendix found in the 1976 Ballantine edition.) Expanded from the serialized version in Astounding, 1942 (according to the review in In Search of Wonder)
