Does it matter? If Mark dies of a massive cardiac event today would all this research and better health just disappear? No. Hearts are damaged very much by genetic susceptibility and stress - and Mark designed his Primal Blueprint ( I believe) with his own weaknesses in mind. He's a tense, stressed and driven person. This has as much impact on his heart as anything else would. That's part of why he has PLAY in the PB, in my opinion. Some people, like me, play all the time. We don't need to write it down, or study it, or try to pencil it in. It happens when we are walking down a hall and decide to do something goofy to a coworker. We don't need it in a blueprint because it's already there. But for tense people, adopting a habit of play will be critical in reducing stress. So I don't care what Mark's stats are, because I am not Mark and his numbers exist in the vacuum of his own life.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
