While the author shares some valid data and makes good recommendations, I believe he misunderstands the concept of intuition. (Intuitive: using or based on what one feels to be true even without conscious reasoning; instinctive.)
A being is intuitive, a piece of matter, such as a body part, is not. There are biochemical signals that produce a variety of reactions in the gut. No little man down there “feeling” or being intuitive.
