This concept of "the science" we've converged on a culture really doesn't make a ton of sense. What does it mean to say "the science" is against a position that many relevant experts hold? To the extent that there is such a thing as "the science", the book the author is advertising (

against it: there's a traditional medical consensus in favor of SBS/AHT, but it's become more controversial, and if you read this book you too will be convinced that it's wrong.
