Many people spend thousands optimising their biology. Fewer spend time optimising the operating system that controls it. You can have the best supplements, wearables, biomarkers, and protocols in the world… But if your mindset repeatedly chooses stress, inconsistency, poor recovery, and self-sabotaging habits, your biology will eventually reflect those choices.
