I got this as a present a while back and hated it. The reason I am writing this review now is that I have recently given it to a cancer charity shop I support (along, I should add before you judge me harshly, with some actually good stuff).
Factoids on the radio are fun throwaway things, but reading a book full of them is painful. You learn nothing, as there is no background explanation, and I am sure that several of them are urban myths, ridiculously oversimplified or simply plain untrue. I won't say which as I no longer own the book and can't make exact quotes here.
This must have been such an easy book to write, but it's far too easy to read and is best suited for people with unquestioning minds who are happy not to know more than a one liner about anything. Books like this make me despair.
