I've been to jail and I could tell you that the one thing mayweather is right now is bored. Jail is extremely boring, there is nothing to do but think and sleep. The food is crap, the pigs behind bars act differently when they know no one is watching but act like they're the "good guys" when they're in public. Peanut butter and jelly sandwiches and small box juices, disgusting meals that taste like rubber is what you eat. If jail is good for one thing it's good for opening your eyes to the reality of what the world really is a jail in itself.

The pressure is psychological, if you can't stop thinking about getting out you're going to break down sooner or later from mental exhaustion. Plus you gotta take shits in front of 20 + grown men and have people take shits next to your bed. Personally all jail did was make me angry and not trust anyone.
