In this season, I have with me again Tim Kelly with Polytope Press.  He is an avid journalist and researcher in the fitness world with an emphasis on the science behind all of our body's systems.  His method of checking/testing our FLOW of each type of pathway we have in the human body is extremely interesting.  Check out this season where he goes in-depth into the most important minerals.  Also, check out his website and books:
