Read: The End Specialist
Drew Magary's The End Specialist (or the USA version The Postmortal) is interesting for (at least) two reasons. The first is, of course, the idea to explore the consequences on an individual and societal level of finding a cure for aging. (Was Malthus right, will we suffer horribly from population growth after all?) The second is the literary style of writing such explorations in the form of a personal (b)log, giving the particular perspective of a single individuum.
While I feel that Magary does not take full advantage of the blog approach, it allows for leaving many gaps (in the time sequence of the story, the protagonist's development, and the details of his fictitious world) that otherwise would be perceived negatively.
The bit parts remain absolutely undeveloped, the political and economic ramifications of the elimination of natural death are not spelled out in greater detail, only minor bits and pieces that have an immediate effect on the protagonist are made explicit. Hence, The End Specialist may disappoint a little on the exploration of the individual and societal consequences of the end of death expectation that the reader may have had before reading the novel. Other science fiction novels do a much better job on this end.
Yet, The End Specialist's moral is clear. “The cure for death must never … be legalized.” At least as long as we all have to stay on earth.
