I'm want to tell you something Mark. Something you do not yet know, but we K-Paxians have been around long enough to have discovered. The universe will expand, then it will collapse back on it's self, then it will expand again. It will repeat this process forever. What you don't know is, that when the universe expands again, everything will be as it is now. What ever mistakes you make now, you will live though on your next pass. Every mistake you make, you will be live though, again and again. Forever. So my advice to you is to get it right this time around, because this time, is all you have."
From the movie K-Pax
