this book should be read in high schools, first because it is almost a novel, because follows (with emotion) brain cancer progression from the author, especially because it allows us to understand life in whole, through food of course (we must eat to live, as the saying goes), but also because of his behavior (exercise, relationships with others) and its dependence on the environment (pollution). the tests are appropriate (pesticides, chemical cocktails, mobile phone ...) and very well documented. the author was also a medical researcher, and it is one of the strengths of this book, that it has moved from observer to position the patient condition. he was able to observe the distress these patients are found and that he developed empathy for them is felt throughout the book.
