Martin Zucker has been writing for 60 years, the last 40 of them about health, nutrition, and fitness. During that time he has written a dozen book and hundreds of magazine articles. His latest book is about the discovery of Earthing, also known as grounding. In the book, he and his co-authors describe the remarkable health and healing power of planet Earth and how humans are largely disconnected from it and unaware that it exists. Reconnecting is easy, and commonly produces significant results such as reduced inflammation, pain, and stress responses, as well as better sleep and blood flow. Zucker is a former Associated Press foreign correspondent.
