If there was found to be an oxygen atmosphered planet in the universe that was populated by friendly, intelligent anthro critters, and you had one opportunity right now, would you give up what you have here on earth to go live there? Why or why not?
Probably... but it would depend on whether or not other people (and critters) I cared able to go. I'd love the adventure, but not at the expense of the people I have. Materially, I'd have no problem walking away.
