I only bought this book 2 weeks ago and am totally enthralled. what an eye-opener on what"s going on with and inside my body, it explains huge question marks I"ve had for years and haven"t found answers for. I"m reading it until late at night, too excited to put it down, reading some pages several times, writing out notes in a whole new notebook all for itself. As soon as this comes out in English next spring I will by many copies and send them to friends and family who have been battling their share of digestive "issues", plus allergies, obesity, cholesterol, diabetes and more. If you are fluent in German buy it now, if not, put in your order for next spring, for the translated version, so you don"t forget. It"s life changing, entertaining, and very very funny. It explains the hidden mysteries and goings on in our most important organ, our digestive system, or gut, to where any regular person can understand it and will be excited to learn more on every page without ever getting boring. It"s a whole new approach and there seems to be a huge amount of research, some of it just getting started. So cool. Order it, buy it, I"m going to be reading mine over and over, it"s totally awesome. Best book I"ve bought in ages!
