Liz Weston

Dear Liz: A letter writer in your column says that “self insurance,” or going without health insurance, “certainly reinforces healthy lifestyle choices.” My husband made all of those “right” choices for more than 60 years, which was absolutely no protection against being diagnosed with brain cancer. Your penny-pinching correspondent might currently be running marathons or doing daily yoga, but as Clint Eastwood put it: “You’ve gotta ask yourself one question: ‘Do I feel lucky? Well, do ya, punk?’”

Answer: As a nation, we could certainly lower our healthcare costs by choosing healthier lifestyles — exercising, avoiding obesity, not smoking and so on. But accident or illness can strike even the healthiest among us, which is why health insurance is a necessity not just to ensure we can get care but to protect against catastrophic medical bills.

Unfortunately, as human beings we often have the delusion that what’s happened in the recent past will continue indefinitely. If we’ve been lucky with our health, we may think that will always be the case. The reality is that everybody’s luck runs out at some point, and often does so at great expense.
