circadian rhythm
A circadian rhythm is the internal timekeeper that sadistically surrenders you to the whims of dawn and dusk. It orchestrates a crescendo of fatigue at every inconvenient meeting and demands a standing ovation for naps at midnight. Ignoring corporate memos and ethical pleas alike, it warps your craving for coffee and slumber into a paradoxical routine. The harder you try to tame it for health’s sake, the more it delights in marching to its own schedule. Ultimately, it forces you into a dual life of espresso in the morning and clandestine dozing at your desk.
