Found this on the daily deal while my husband was undergoing emergency surgery, finished it just as our friend a retired Airline Captain arrived for a visit. Discussing what I had read about checklists really brought the book alive. He shared stories of his own experiences and confirmed its accuracy in every detail. But that is Gawande, what he writes flows so easily that I always have to remind myself of the incredible amount of research that is behind his words. He has proved the value of the checklist to just about anybody, working in any field, who may choose to buy the book. So, a very valuable read, but prepare to be entertained as well. Please be sure to check out the acknowledgements at the end to gain an appreciation of the depth and breadth of the author's research.
