You might be tired because the energy-producing engines in your cells (mitochondria) have become less efficient at making energy. No amount of coffee can fix that.
By midlife, those structures are degrading, generating less power, triggering more inflammation, and recovering more slowly. The result is you feeling more fatigued doing the same things you used to. Think of it like a car that sputters not because you’re driving too hard, but because the engine’s parts are worn out.
