How when one is smart to understand what happens to us (cancer), to answer questions that arise each: why me, what have I done wrong, what are my risk factors? It's trying to understand what happened to him that DSS began his quest, ce'est because it is part of his therapy he wished to transmit. It's simple, clear and logical even if all is not shown. We discover what to do and not to do, what to eat (preferably) and what not to eat, how to respond and not react. Above all is consistent with what preceded and what followed and consistency feels good. Without thinking you read the facts that are referenced in major medical journals in the world like "the New england Journal of Medicine" or "Journal of Proceedings of the National Academy of Sciences" with more than 300 references but clear and it is understandable French. Hat for making it understandable to everyone. At the end we are pumped up, we know where we're going and how to do it, there is more to .... and if you have the blues (because many things have to change) then I would advised to read one again. This does surprises me more than it was envied (for its success), copied but never equaled. Read almost closed eyes and meditate especially. Bravo
