Reviewed in the United States on September 2, 2018
Raised as a child in the Sandhills of Nebraska without electricity I had a pretty accurate circadian clock, but lost it with city life, night work, etc. This book contains excellent information on the importance of the circadian sun clock for every organ in our body, especially the brain, and the separate twenty-four hour clock of our digestive system. Strongly recommended. Most important and critical health research within the past twenty years and the author is the primary researcher in this field.
