Get an extremely high deductible catastrophe insurance for your family.
For my family of 4, with the exception of the years I gave birth to our 2 kids, we never reached our out of pocket deductible. All healthcare was routine physicals, an occasional sick visit to the pharmacy, virtually no prescription drugs, no specialists, etc. That went on for 10+ years. We also had no family history of diseases that affected people under 50. Sometimes insurance seemed like a waste of money.
Then out of nowhere several years ago, my 13 year son was not well. It was cancer. After hundreds of thousands of dollars of chemo, it was determined he needed a bone marrow transplant. He had one, survived, and he is now 18 and doing well. In the last 5 years, we've had $3 Million of medical expenses. Just one of the drugs he took (a pill) costs $11,000/ month. We would get bills for around $300,000/ month. Every month. For more than a year. The worst month (his transplant) our hospital bill was $789,000. (part of qualifying for the transplant was proving we had insurance to pay for it). And that was 4 years ago, so I'm sure prices have gone up.
Trust me, when your world is falling apart, you do not want to even try to self pay for this or even have to worry about paying for this. Cancer or other disasters are EXTREMELY expensive and only the exceptionally wealthy can afford to self insure. Also remember, as your world is falling apart, you are less likely to be able to work more, get a new job with new insurance, etc. "I'll just go back to work" is not a good plan.
Just because lightening doesn't strike often does not mean it is smart to stand in a field during a thunderstorm holding a golf club.
Please get insurance.
