I think alot would depend on which prison and security level. Big difference between doing time at a prison like Trenton State and doing time at Bayside(used to be Leesburg)

Not even talking about doing it for money but if i really had to do a stretch i think my mental limit would be 5 years. If i thought i was going away for anything longer then that i would go into the wind. But anything less then 5 years isn't worth running for the rest of your life so that would be my max.
