Stress doesn’t just live in your mind — it leaves a measurable signature in your DNA. At the ends of every chromosome are telomeres, microscopic buffers that protect genetic material during cell division. Each time a cell divides, these caps shorten. When they become critically short, the cell loses its ability to function and repair. Chronic stress accelerates this process. From a medical standpoint, this isn’t abstract. Prolonged activation of the stress response increases cortisol, inflammati
