I really enjoy doing these and this one was a special treat.
Mark is an advocate of intelligent, brief, intense exercise and practices the carnivore diet which he credits with dramatically improving issues he's had with autoimmune ailments.
Mark is a super nice guy with whom I share many commonalities
but mostly, I like the combination of his critical thinking, and "humility" (awareness of confirmation bias)..... as well as his respect for those who may disagree with him.
On facebook, look for Mark Strough OR Mark of Health OR Mark n Lori Strough OR Mark's Health and Nutritional Group.
