When a body is sick, the ancient Galenic tradition said, look first at the regimen — not the remedy. This sounds obvious until you realize how thoroughly modern health culture has inverted it: we treat symptoms aggressively and then wonder why the same patterns return. The 19th-century physiologist Claude Bernard had a more radical framing — he argued that disease isn't something that attacks you from outside, but a failure of the body's *milieu intérieur*, its internal environment, to maintain the conditions life requires. Illness, in this view, is a collapse of regulation, not an intrusion of enemy forces. That reframe matters practically: it shifts the question from 'what do I take to fix this?' to 'what conditions am I failing to maintain?' The body doesn't need conquering. It needs a stable enough environment to do what it already knows how to do.

What would someone observing your daily routines say you're actually optimizing your body for — not what you intend, but what the evidence of your choices suggests?
