so the finest praise i got for my book from helen sandler that the book brought her story to a close, and robert sandler found a rightful place in medical history and he decade-long haunted memory came to an end. and that was finer praise than any i have received, and perhaps the most moving thing that happened to me around the book. i think i have time for one more passage i'm going to read, and this from the end of the book. and which takes up a very different kind of challenge. the first kind of challenge i described to you is the challenge of storymaking, which is how you pop late a book. so at it the challenge that appears in the content. a book like this also faces a different kind of challenge and that's the challenge of summary-making, which is how do you summarize 4,000 years of history. how does one tie up all of this? the quick answer is, there is no simple solution, and that's something you learn in the book. one of the challenges of the book is, is there no pat answer. i didn't want to write a book, this is how you cure cancer, like eat broccoli or some nonsense like that
