So let's say you have a spaceship that can transport you anywhere at near the speed of light and you can go into hypersleep. So it can fly around until it finds a planet with oxygen that you think is pretty. Do you leave earth knowing you could never come back (at least not to see anyone you knew)?
To me I think the adventure would be too great to miss out on.
Plus don't forget double teaming can be fun if she's into that.
