This book was a lot of fun, and I enjoyed it. Someone bought this for me for Christmas close to a decade ago, I think as a joke.

Though the book is a joke, it takes itself and the subject seriously, which makes it funny. 

The physiology of zombies isn't real, but this book acts as if it is, and explores it. Since reading this book, I can't help but think about it every time I see anything about fictional zombies. Most films and shows show us zombies that don't even try to make sense. Even if re-animation were possible, it wouldn't enable them to move at high speed, as they would have less and less oxygen in their muscles each second. Fiction has to have some grounding in reality or there are no clear stakes in the story and we as an audience don't have much fun when rules are made up on the fly, or things are happening just because of "magic".

I know this isn't an important subject, and this isn't an important book, but I liked it.
