Does preventive healthcare actually save money in the long run, or is it just shifting costs around? I've been tracking my own insurance claims for five years, and the annual physical plus screenings caught my high blood pressure early, avoiding a costly ER visit last year. But a friend without insurance skipped checkups for a decade and now faces dialysis bills that dwarf any prevention cost. Still, I wonder if the system benefits from people like me paying premiums without needing major care, while the uninsured only show up when it's catastrophic. Maybe the real answer depends on whether you measure savings for the individual or for the whole insurance pool?
