Ham Ik, a disease specialist, analyzes that modern people's fear of disease is a result of the rapid development of medical diagnostic technology and the subsequent expansion of disease names, rather than the actual deterioration of health. In the past, behaviors that were simply dismissed as impatient or distractible are now categorized under specific diagnoses such as ADHD or autism spectrum disorder and are captured in statistics. This clearly has the positive aspect of early treatment, but on the other hand, it is also a major cause of the illusion that humanity has become sicker than in the past. Director Ham emphasizes that advances in medicine have not made people sicker, but have simply made invisible areas visible. Therefore, I advise that the first step to a healthy life is to break away from ‘health anxiety’, which is excessively absorbed in new disease information and confines oneself to the frame of a patient.

Regarding the increase in serious diseases such as shingles and cancer in young people, Director Ham diagnoses this as a decline in immunity resulting from a breakdown in lifestyle habits rather than environmental factors. If humans in the past had a weakened immune system due to lack of nutrition, modern people ironically are weakening their own immunity due to excessive stimulation, lack of sleep, and lack of exercise. The fact that shingles, which was commonly found only in people in their 60s and older, is also found in teenagers clearly shows a cross-section of modern society in which sleep, the basis for physical recovery, has collapsed. He asserts that maintaining a regular lifestyle that balances the body and mind is a tens of thousands of times more effective method of prevention than spending time searching for external drugs or vaccines.

He also maintains a cool-headed perspective on excessive fears about infectious diseases. Respiratory viruses such as COVID-19 mutate to survive, going through a natural evolution process in which their infectiousness becomes stronger but their virulence becomes weaker over time. Since these viruses will continue to appear repeatedly throughout human history, the most powerful defense is to strengthen one's own immunity rather than being afraid each time. In addition, he emphasizes the dangers of smartphone video exposure and the importance of face-to-face contact between family members in relation to developmental issues in infants and toddlers, emphasizing that physical emotional connection rather than digital devices is the key to helping children grow healthy.

When discussing quality of life beyond health, Director Ham also provides deep insight into life and human relationships after retirement. Many people view retirement simply as the end of their career, but in reality, they go through a period of ‘retirement purgatory’ where their roles and daily rhythms are completely reversed. During this period, taking care of one's body, forming meaningful relationships, and being psychologically flexible to adapt to the transition period of a new life are as essential as financial preparation. In addition, as we live in harsh times where people feel lonely because they cannot trust people or, on the contrary, are easily trusted and hurt, we must reflect on the values ​​of freedom and responsibility and overcoming feelings of inferiority suggested by Adlerian psychology. Even in the face of problems with no end in sight, such as the treatment of chronic skin disease, finding a realistic solution by safely reducing medication with an expert rather than stopping treatment out of vague fear is the true restoration of healthy daily life.
