Your brain isn't responding to the world. It's responding to what it thinks the world is. In this episode, we explore the physiological consequences of thinking - how belief, expectation, interpretation, and meaning can literally change the body. Not metaphorically. Biologically. You'll hear about the knee surgery that "worked" even though the surgery never happened. Parkinson's patients whose brains released dopamine because they believed they were medicated. Hotel housekeepers who got fitter, leaner, and healthier without changing anything except how they thought about their work. Athletes who got dramatically stronger because they believed they were taking steroids - when they weren't. And a bloke who nearly died from an overdose that didn't exist - the nocebo effect in full flight. Enjoy.
