Luckily, in the decade I had no health insurance I did not get sick. My children were covered by their father's excellent insurance but I lost mine when the divorce was finalized.
When people who cared about me suggested I get an annual physical and routine screenings I always put them off. I knew a 'pre-existing condition' would preclude coverage when I got a better job and had more benefits. So I gambled. And I worried. My gamble paid off. Even though I am in several high risk categories, I developed nothing serious and eventually I got a good job with good benefits.
But I will never forgot the days and nights I worried. The sleep I lost when I thought, "What if...."
No one should spend a decade wondering and worrying. Obama took those concerns away from millions of people when the ACA went into effect. Access to affordable healthcare is a human right, not an entitlement.
