There's a great deal of useful information in this book, but you will have to overlook the stereotyping, some of which is hasty generalization. For example, the ability to read maps is not dependent on gender (this statement is being made by a woman who can, in fact, read a map). Also, the section on farting, though humorous, is also inaccurate. Perhaps, during the more prudish 1950s or so, more women were offended by their husbands' farting, but I don't see this today. In fact, in my marriage, it is my husband, not I, who is shy about it (and other bodily functions).
Anyway, there's enough good information in here to make this book a worthwhile read. I especially like the chapter on the "points system."
