Chapter 1: A Routine That Never Changed
For many people, a cup of black coffee is the perfect way to start the day. Rich in aroma and low in calories, black coffee has long been praised for helping people stay alert and focused. For one 50-year-old man, however, coffee was more than a morning beverage—it had become a daily ritual he followed for years without interruption.
He often drank several cups throughout the day, believing that black coffee was healthier than sugary drinks or flavored beverages. Because he rarely added milk or sugar, he assumed his habit carried very little risk.
At first, everything seemed normal. He remained active, continued working, and rarely thought about how his daily choices might affect his body in the long run. Like many people, he paid little attention to hydration, sleep quality, or routine health screenings.
Over time, subtle symptoms began to appear. Fatigue became more frequent, and he occasionally felt discomfort that he dismissed as stress or aging. Since the symptoms were mild, he continued his normal routine without seeking medical advice.
