In theory, a year of human life is priceless. In reality, it's worth $50,000.
That's the international standard most private and government-run health insurance plans worldwide use to determine whether to cover a new medical procedure. More simply, insurance companies calculate that to make a treatment worth its cost, it must guarantee one year of "quality life" for $50,000 or less. New research, however, would argue that that figure is far too low.
