My guest is P. D. Mangan. He is a writer and commentator on health, fitness, and life extension. He's also authored six books.

He overcame chronic fatigue largely through his own efforts. Now at 65 years old, he's in better shape than most men half his age.

On this episode, P.D. talks about how early humans evolved—the way hunter-gatherers lived, worked, ate and slept.

We discuss how mainstream health authorities screwed everything up, why their ideas are mostly wrong, and what you can do to be truly healthy & fit.

P.D. believes you can extend your lifespan and healthspan.
