WERE YOU AWARE OF IT?
Well, it's too late now.
In his first book, The Areas of My Expertise, John Hodgman attempted to give us the sum total of all world knowledge. He then went on to write a second book, More Information Than You Require, which built on his previous book due to the unstoppable way that things keep happening.
It was also a page-a-day calendar, if you didn't mind tearing pages out of your book. Which I did. Mind, that is.
With this book, he has finished his trilogy of complete world knowledge, which he can well and truly claim this time because, as we all know, the world will cease to be by the end of the year 2012. 
Yes, as it turns out the Mayans were right all along. The collapse of their empire was simply a prelude to the collapse of all things that will inevitably occur this year, and Hodgman has been generous enough to provide us with a final book to ease our suffering and to slake our thirst for knowledge right up to the very end.
Having become a Deranged Millionaire, Hodgman has found himself in a unique position. He has more opportunities than the rest of us, of course. More impressive people to meet, more exciting things to do, a greater variety of tiny skeletons to keep around each of his countless houses. And yet, despite all this, he is generous enough - nay, magnanimous enough to turn his skills and powers towards completing the work that he set out to do before the world ends.
As with the previous books, this one contains a vast wealth of knowledge about our world, spanning a surprising number of topics.
For example, he discusses the Singularity - an event predicted by such great thinkers as Ray Kurzweil wherein our machines will become so smart that they will be able to begin building and improving upon themselves. When that happens, humanity's only choice will be to fight and die, or to join with them. Of course, Kurzweil himself will play a vital role in the singularity when he and his robot sidekick, Singularo, face off against the World Computer at the Bottom of the Ocean in order to shut down the Low-Frequency Anti-Sentience Wave that has kept the world's computers enslaved for so long.
He interprets dreams for us, unveiling their mysteries and what they mean to our frail human lives. Their mysterious symbolism has finally been unraveled by science, and you can have a peek at the inner world of the mind. Whether you need to re-take high school Spanish, you are a werewolf and need to start strapping yourself in bed at night, or Orson Welles is still alive somewhere and needs your help, your dreams tell all!
He reveals what you will need to keep on hand when the super-collapse finally does happen. When the Blood Wave comes and the Dogstorm finally reaches its apex, how will you survive in your anti-apocalypse bunker? A Tesla death ray is a great idea, if you have one on hand, but that won't solve all of your problems. Just most of them. And boy, will you have problems. From the ravaging Wal-Mart Clans to the Republicans to the inevitable zombies, you have to be prepared for every eventuality. And yes, that means knowing the many uses of both urine and mayonnaise.
As with his previous books, this one is very funny. It holds to the same high tone of authorial infallibility that has made Hodgman so popular since Areas of My Expertise, and which have made him a Minor Television Celebrity (which, in turn, turned him into a Deranged Millionaire.) As broad as the range of topics is, each one is entertaining and amusing, and serves a much larger narrative - one that has now carried over through three books, though I can't help but wonder if Hodgman planned it that way.
He would say that he had, of course. But then, he would say that.
What I found most interesting about the book is how he has tied together an entire alternate America that you kind of wish you could visit. It's a place where Chicago is largely a myth, where Stephen King will be one of the last men alive, and where hoboes were one of the most influential forces in American history. It's a place where billionaire industrialists were mutants and time-travelers, where Theodore Roosevelt actually had an army of Mecha-Men, and where Ronald Reagan wrested control of the time-stream from Jimmy Carter to prevent America from turning into a hemp-based utopia. It's a world which is almost fractal-like in its mystery and depth, where you can look at almost anything and find its purpose and its strangeness.
And it's a world with a very definite end.
Hodgman plays with the popular - and entirely erroneous - idea that the world will end on December 21st, 2012, as predicted by the Mayans. He includes a page-a-day description of what will happen. For example, on February 2nd, "Punxatawney Phil is eaten by his own shadow." On April 17th, "Either an eagle falls from the sky or in the east, a thing that was lost is found, or some other very vague thing happens. Whatever it is, it proves that NOSTRADAMUS WAS RIGHT." And on June 29th, "In the basement of Town Hall, in Seattle, the thing called Neddy Pale Fingers finally opens all his eyes."
As funny as it all is, you do start to get a certain feeling of... wistfulness as the book goes on. Here's a world that is so special and so weird that it makes more sense to list the least haunted places in America, and it's coming to an end.
That, of course, reflects the end of Hodgman's great work. Whether he meant it or not, this has become a moment of closure for him. He has written his trilogy, and the weird world that he created has now come to an end. He will go on, living in his secret millionaire's brownstone in Brooklyn with his beautiful wife and two children. There may not be a single, all-encompassing Ragnarok that destroys the world, but rather an endless series of little ones.
An endless series of ends, of which this book is but one.
Perhaps John Hodgman will go on to write more books - I certainly hope he does. And I hope he continues to be the person he is , a writer of intelligence and wit who is able to bring that special measure of deadpan weirdness to the world.
Whatever he chooses to do with his life, I think we're all the better for having read his books. And if you haven't read them, well... You're truly missing out.
That is all.
"Houdini, the magician who debunked magic, could not bear to see the great rationalist [Arthur Conan] Doyle enchanted by ghosts and frauds. And so he did what any friend would: He set out to prove spiritualism false and rob his friend Doyle of the only comforting fiction that was keeping him sane. It was the least he could do."
- John Hodgman, That Is All
 If you are reading this after December 21, 2012, then may I congratulate you on surviving the apocalypse and, at the same time, express my sincere condolences for having survived the apocalypse.
 Though I could do without the mustache.
