I noticed this title in the list of "Other Works By" page in a Conn Iggulden book I read recently. The title alone was enough to get me interested and I looked it up online. I read off the description to Journey and it was decided that we needed to own this book.
Made to look like an old 1950s text book (it was actually published in 2007), this is a great book - I haven't done more than flip through it so far and I already know this for a fact! It includes everything from how to tie knots, to the Navajo code-talkers dictionary; coin tricks to famous battles; star maps to interacting with girls. Before you get too 'excited' about this last, it's things like "When you are older, flowers really do work - women love them. When you are young, however, there is a ghastly sense of being awkward rather than romantic - and she will guess that your mother bought them."
And with the economy the way it is, some of the things in here may be of more immediate use than simply a good laugh.
Although, I do have to agree with a question Journey had about the book. After reading the description, she asked "Why is just for boys? Those are the kind of things I wanted to know too!" Well, now we'll both know!
