Just been mulling this over recently. My nutrition, sleep, exercise and all the trappings of Primal Living are fairly dialed in. I certainly feel better than ever; recent tests have shown all parameters (lipids, allergies, inflammation, blood pressure, dental health, etc) have all optimized. My body composition, functional strength, flexibility, etc are as fine as I can ever recall (turning 42 in May) through my life.
I am comfortable with Primal Living and it is far more than a habit at this point. I do continue to read some books, and blogs that promote (as well as those that oppose our view: low fat, vegetarian, cardio based, etc) and this only reinforces this is the correct human lifestyle! Yay!
It seems quite plausible, and I fully expect, to live out my days with zero need for further medical testing, intervention or fiddling. Barring a broken limb, an injury, trauma or infection, I should think Primal Living should carry any of us Primals through life without the myriad procedures, drugs, tests and interventions that are SOLD to the public daily. I plan on being that old spry guy still living independently in his home, that just doesn't wake up one morning long into his life.
Wish I could opt out of paying for CW based health care and dietary/lifestyle recommendations that just make folks sick.
