Title lying 2

I bought this book to give to my husband, thinking it would be a book on the new technologies of the future.
This is actually more of a diet book that a scientific book. My dear husband was very disappointed because this does of course not meet its expectations.
Yet I read it, and I must admit that even if the title is not representative of the content, it is nevertheless of good quality and really interesting ... extremist and chouilla too.
In short, a failed gift.
