You made me check your assertions, so I did.
I don't see that you have to have it and I don't see why noone will take Medicare without it. Furthermore I don't see how it affects you and WHY they "don't take Medicare". Based on stuff I read, you are better off now than you were before.

Anything this is wrong about, you can correct it here. Go for it.
