Obamacare (PPACA) sets a price on the value of each year of your life. If the cost of treatment exceeds the "value" of your expected remaining lifespan (as determined by IPAB, a group of government bureaucrats)... YOU WILL NOT GET TREATMENT.
Let's take a real life example from England, where they already have these guidelines. A 66-year-old woman slipped, fell and hit her head. She came to the hospital unconscious due to the bleeding (subdural hematoma) that was compressing her brain. This is a life-threatening emergency.
The Neurosurgery (Brain Surgeon) Resident doctor recognized what was happening and started getting her ready for surgery to stop the bleeding and drain the blood from her brain. As he was shaving her head, the Chief of Neurosurgery walks up and says "What are you doing? You have to STOP that right now! She's 66 years old... she goes to the Recovery Room, (not the Operating Room)".
The Resident doctor says, "Are you kidding me... we can save this woman's life... this surgery is easy... it's 'bread and butter.'"
"NO... she is 66 years old... she's over the age limit... she goes to the Recovery Room," orders the Chief of Neurosurgery.
They watched her die over the next 3 days.
