Query: Only for readers with very limited experience.

This book can only appeal to readers with very narrow experience, because all it can offer is easy to deduce for anyone with average intelligence. This book is cheap in appearance and content, even some of the illustrations are not consistent. Further, there is too much spinning of yarns on general topics and there is very little text on body language signs and techniques, very little.
