These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
"Funny Aneurysm" Moment: The protagonist is an elderly man who was cured of both age and Alzheimer's Disease. One segment of the book deals with fictitious novels written by Terry Pratchett in the intervening 20 years or so between the book's writing and near-future setting. Several years later, Terry Pratchett himself was diagnosed with a form of Alzheimer's Disease.
