A decent book that answers questions like, "why is the sky blue?", "where did the rock, paper, scissors game come from?" and "how can a fire be made without matches?". Some of the answers are very interesting indeed, and it makes for good, light reading. Some of the questions are R-rated as well, so it is more geared for adults.
I give this one 3/5 stars because:
1) I question some of the conclusions. The author, Andrew Thompson, is a lawyer in real-life (not an expert in what he writes about), and more importantly, he cites no evidence. For example, Thompson claims that whether we landed on the moon or not and whether homosexuality is genetic or not are inconclusive, when, from my research and education, both topics seem overwhelmingly conclusive (we landed on the moon and homosexuality is genetic). In his defense, this book is meant to be a bathroom reader more than a scholarly work.
2) The look of the book is pretty drab. It is one thing after another, in no particular order, and all of the photos are stock photos (no historical photos/documents, etc.).
Overall, a decent book and the reader will learn some fun answers to many of life's intriguing questions.
