Why the body-mind link isn't a metaphor. The biology connecting physiology, mentality, and how habits actually form.

Not a sequence. A loop: each of these three feeds the other two, in both directions.

Choose a system below, or click the diagram, to see the mechanics, where it shows up, and what to do about it.

The direction most people get backward

“Mind over matter” gets it backward half the time. Your body runs your mind at least as often as your mind runs your body, through these three systems. When something feels like a discipline problem, check whether it’s actually a physiology problem first.
