Once the wet wollen toque has been pulled off of your face and you see the light of day, for perhaps the first time - why would you ever go back?
Not to offend the mentally challenged, but the only way one would ever go back is if they were crazy at some level. Extreme depression perhaps?
Or you might end like that guy in the Matrix who made a deal with Smith to actually GO BACK in to the Matrix.
He preferred the fantasy world of the Matrix to the challenges of the REAL WORLD.
Cypher:
"I know this steak doesn't exist. I know that when I put it in my mouth, the Matrix is telling my brain that it is juicy and delicious. After nine years, you know what I realize? Ignorance is bliss."
Of course, Cypher was a complete idiot.
