The Dangerous Book For Boys is apparently quite a phenomen. What I loved was this part of the interview with the author who had to make some adaptions from the British to American versions of the book:

Amazon.com: What knowledge did you decide was important to add for American boys? I notice in both editions you have an excellent and useful section on table football, as played with coins. Is paper football strictly an American pastime? I'm not sure I could have gotten through the fourth grade without it.

Iggulden: I like knowing the details of battles, so Gettysburg and the Alamo had to go in, along with the Gettysburg address, stickball, state capitals, U.S. mountains, American trees, insects, U.S. historical timelines, and a lot of others. Navajo code talkers of WWII is a great chapter. It probably helps that I am a huge fan of America. It was only while rewriting for the U.S. that I realized how many positive references there already are. You have NASA and NASA trumps almost anything.

As for paper football, ever since I thought of putting the book together, people keep saying things like "You have rockets in there, yes? Everyone loves rockets!" Paper football is the first American one, but there will be many others. No book in the world is long enough to put them all in--unless we do a sequel, of course.

Wish this book would be the Dangerous Book for Children. Might lead to some more well-rounded girls. Or at least some girls that enter my profession.
