There were enough interesting math shortcuts in this book to keep my interest, especially those dealing with multiplication tricks, squaring, finding divisors (and why those tricks work), and figuring out any day of the week in the Gregorian Calendar. But, there were also many parts that just weren't feasible to me. Only certain people, like the author, are capable of doing all the mental tricks he covers. Some math problems were just too much to do with paper and pencil, and I'm a math person! The other cricism I have is of the last chapter, the epilogue. It doesn't seem related to the rest of the book.
The author had a lot of good insight into how to keep your marriage alive and keep the focus on you as a couple. Many of it was common sense, but I think people often forget how important it is to make time for one another. Better to borrow it from the library than purchase it, but I would recommend it.
