"What a Bummer! A lot goes on down there - more than you can imagine. Now we can all know what goes on and it is told to us in a way that we can easily understand. Clearly written, with one topic leading to the next, Bummer delves into the workings of our bottom end. Filled with important health information and humour. Thank you, Dr. Marcus."

"Bummer illuminates all the issues that exist 'where the sun don't shine.' In this very informative book, Dr. Marcus Burnstein lays out various anal and colorectal problems in an understandable, easy-to-read fashion that patients (and their physicians!) will benefit from tremendously. One of our favourite sections is Dr. Burnstein's reflections on what it means to be a surgeon and how he tries to pass along that legacy to his trainees. Bummer is an important offering from one of Canada's most highly respected colorectal surgeons, and is for all those interested in what goes on with the back passage."
