Input: This book is very disappointing...I expected so much more...there are many interesting things here but none of them seem to be the result of an honest investigation...The author may have some valid points and this book might help someone who really has no clue what he is talking about.... But as a scientist I would never recommend it for anything other than my curiosity and perhaps that could come later....The title just should not carry such large weight on most people...
Output:
Bad review
