This short story begins with a summary of the tale of Guillermo Blake, who believed that "the five senses obstruct or deform the apprehension of reality." The narrator then relates the tale to his own experience: upon visiting his gerontologist for a check-up, he is informed of a procedure that confers immortality. The "immortals" are reduced to living brains within wooden cubes, their bodies having been replaced by "formica, steel, plastics." The narrator tries not to show his horror, but moves immediately to a different part of the country under an alias.
