When I started reading this book I hoped it would be about centenarians and offer clues into their miraculous longevity, but instead the author's digressions are frustrating. Half way through the book and we realized much of the book is about the author, her marriage, and even a visit to her psychotherapist (!).0 Many paragraphs are like reading an on-the-road travelogue as the author describes scenery and environs to and from her interviews.Do we care? How is it relevenat to the secrets of centenarians?Important questions are virtually ignored: what's their spirituality/relligious beliefs? diet? excercise? etc. Instead the author asks innane and irrelevant questions such as "What was the dust bowl like?" as if there are not already written accounts found in any library? Maybe the author doesn't mind wasting time figuring she too will to 100, but I sure can't say that about myself. I don't like my time wasted.
