garyebickford asks: "Slashdot discussions on the SpaceShipOne flight talked about whether folks would take the flight if offered. It reminded me of a question that used to go around. If you were offered the opportunity to move permanently into space - perhaps an orbital environment, or asteroid (mining?) or another planet, etc. - and you had an 80% chance of living five years, would you take it? What if your chances were 50%?"
