As FxMed docs, we’re committed to working with the body’s own capacity for health. Dr. Josh Mitteldorf offers a contrarian strategy, one which he says is grounded in a new breed of evolutionary medicine. He tells us that diseases of old age are qualitatively different from the diseases we get when we’re younger, different because in old age, our bodies are part of the problem, not part of the solution. Aging, says Josh, is the body deliberately destroying itself (for the sake of the population), via inflammation and apoptosis and autoimmune diseases. In this interview, Josh and I find common ground talking about hormesis. In Josh’s theory, the fact that the body lives longer when stressed (e.g. caloric restriction) is proof that the body isn’t trying its hardest to stay young when it’s not stressed.
