They will say that they have to do this because of global warming and the carbon footprint from old sick people using up too much energy and resources (who have no "quality of life" or "productivity" - the "useless eaters"). It's madness. Malthusian population control. Obama is the puppet of the secret societies promoting this. They're probably already tabulating the carbon footprint savings of early deaths from the BP Gulf oil spill.
If those ghouls got their way they'd prolly put Stephen Hawking at the top of the list.
After all look at the fossil fuels he uses to stay alive and the massive Carbon Footprint that follows him. And since he hasn't contributed anything to Physics in decades what's the point of having him around any longer.
So sorry Stephen, thanks for all that Black Hole stuff, but it's off to the Death Chamber for you now.
