SBS program <Discovery of Knowledge> posed this question to Professor Chang Hyung-woo of Seoul National University Bundang Hospital, widely known as the "Agu King" doctor: "Professor, can't we live as a 'healthy pig'?" Professor Chang's answer was short and clear. No such thing exists, he said. Emphasizing that it is only a matter of time, Professor Chang stated that obese individuals will inevitably pay the price for it. Professor Chang even mentioned that upon seeing North Korea's Kim Jong-un, he thought to himself that Kim must be having an even harder time than he used to because he is more obese. We listened to his past story of how grueling it was, how his life changed after escaping obesity, and his everyday life now.
