Well i wouldn't pick anyone, because they would have to live in barren waste land until death comes around, and it wouldn't be a good death (not saying there is one) but it would be slow and painful, like starvation or of a disease or just old age depending on who it is.
Would they be stuck alone on an empty planet or would I be there, too? Is this one of those things where you have to repopulate the earth? This is a creepy question. But in answer... Eh, I can't answer. Too creepy in the context I have placed upon it.
