Group 1 - The core viewpoint emphasizes that health investment, particularly through annual health check-ups, is essential for early detection of potential health risks, serving as a foundational element in a health investment portfolio [1] - Health check-ups are defined as broad risk detection tools aimed at identifying high-risk indicators among asymptomatic populations, while clinical diagnosis involves more targeted and sometimes invasive procedures [2] - The inherent uncertainty in medical science is highlighted, focusing on the balance between sensitivity (correctly identifying disease) and specificity (correctly ruling out disease) in screening tests [3] Group 2 - The complexity of diseases and their hidden nature pose challenges for health screenings, as the timing of the check-up may coincide with a "window period" where diseases are not yet detectable [4] - The importance of targeted screening for high-risk populations is emphasized, suggesting that routine check-ups should be complemented by more in-depth and specialized screenings to improve early detection rates [4] - The article advocates for a shift from viewing health check-ups as absolute guarantees of health to a dynamic management approach, where regular check-ups create a continuous health monitoring system [5][6]
