Medical care can be very hard if you do not have good insurance. My friend's medical insurance company cancelled her insurance retroactively after she had a heart attack shortly after enrolling in the insurance plan. She is too young for Medicare. While she was hospitalized for the heart attack, they found a sinus tumor in her head, later found to be cancerous. She now has no insurance, little chance of ever getting any, a $300,000 hospital bill that she is paying a little on every month, and is struggling to get her cancer treated.
I think every legislator should have only the same opportunities to get medical insurance as the rest of us have. . . boy, would things change fast.
