You decide you need a little fresh air, so you go outside for a little stroll. Because you don't expect to be out long, or do anything of note, you leave without your wallet or purse and have no identification on you.
While you're walking, a car goes out of control, jumps the curb and mows you down. You're knocked unconscious and you have several life-threatening injuries. An ambulance quickly arrives, scoops you up and brings you to the hospital where they have no idea who you are or if you are able to pay for the care you need.
Should the hospital treat you or should they wait until they can make certain you can your bill for the care they're going to give you?
Just a refresher for some of the more important points:
1) You're at the hospital
2) You're unconscious
3) The hospital has no idea who you are of it you can pay
4) You're dying
