This model has clinical utility. It generates treatment protocols. But it increasingly fails to account for observations that don’t fit: the paradox of centenarians with <em>low</em> T3 outliving their euthyroid peers, the metabolic stasis of hibernating mammals, or the catastrophic symptoms reported by individuals on restrictive diets whose bloodwork looks entirely “normal.”</p>
