My husband is actually currently in recovery from a broken pinkie finger, so this title caught my attention. I picked this up yesterday, and I've just finished reading the whole thing. I didn't want to put it down, because so many of the facts are really interesting!
I really enjoyed reading this book. Probably about 20% of the facts were relevant or very interesting to me, maybe 65% of the facts were moderately interesting, and 15% of the facts I was not at all interested in (basically, the sports ones and some of the bug ones). I'd say probably less than 5% of the facts were things I already knew about.
The author includes a list of sources for all of the facts, and a pretty thorough index. The author does a pretty good job of mentioning where different "facts" may be considered controversial, but with one source listed per fact, I do wonder if there is a lot more dialog on some of the facts than is written; in any case, this book is not an exhaustive reference, so that's all right.
I don't know how many of the facts will really make me wealthier, healthier, or smarter than others, but they made for some interesting conversation with my husband, anyway! Many of the facts were about new things that may come up in conversations later (for instance, a potential duct tape replacement!) and maybe I'll feel smarter when those things come up and I can say "Oh, right, I've heard of that!"
There is something in this book for everyone, I think. I would really recommend this book for reading with interruptions. This is perfect to read while you're waiting for things, because it is broken up so well into questions and answers. It is ideal for a waiting room, coffee table, or bathroom, etc. I carried it with me in my purse while I was reading it. It would also make a fun birthday gift--but there are a few pages that have facts about adult topics, so you probably don't want to give this to your friend's 9 year old (even if they love facts).
