Preventive health is the cornerstone of a long, vibrant life. While many people only visit a doctor when they feel unwell, regular annual health screenings can detect potential health issues early, long before they develop into serious illnesses. By following a structured health screening checklist, you can take control of your well-being, reduce the risk of chronic diseases, and maintain optimal health at every stage of life.
