Would you be one to sign up and leave for another planet or a life aboard a space vehicle or would you simply want to end your family line on good old planet earth?

What factors would influence your decision?

If the "ark" ship were only 100 couples, would you hesitate, verses it being 1000, or 10,000 couples? Would you go if you knew there was a set destination a few years or decades away? What if it was a "multi-generational" ship, where you knew that YOU would never see the "new world" but your great, great grandchildren might? Would it be worth the chance?

This is a real thought question.
