Earlier this year I had a cardiac MRI. You slide down the MRI tube and they inject gadolinium through a vein in your left hand. There's a cold sensation that runs the length of the left side of your body, which is fine until it reaches your head (brain). You sort of want to cry out, but you also don't want to be a wimp about it, and it passes.

Here's the bill: $7,056. I always think about medical bills in terms of Mercedes payments. You can see that my cardiologist pays about $2,846 a month for his S600, so the cost of the cardiac MRI will make almost exactly two and a half car payments for him. Guess who doesn't want a Single Payer healthcare system in America?
