Query: Obesity Cancer Depression: Their Common Cause & Natural Cure

This book is an eye opener and many will dispute its content. I do not!!I have witnessed first hand, the miracle of a life returning as a patient was given saline (salty water). While working as an R.N. in an Emergancy Department, I watched a patients monitor signaled a life threatening drop in his blood pressure. The doctor was yelling at me to get a huge bore cannula into the vein, and get that saline in, as fast as possible. It was a rush with time, but as the saline surged into the patients veins, his blood pressure rose to normal. Have you ever watched a long distant race on the T.V. only to see the runner collapse and die as a result of heat stroke... Their body fluids have dropped below normal,and the simple fact is, they were dehydrated!This book, by a medical doctor explains the scientific process of how our body needs water.. and why?
