here's something wrote:Mostly troll responses, but a few good ones:
Just read through the thread, and it looks like this one is going to have the same types of answers by how it's going already. They have no clue, and that's a good thing. What people always miss (even though the OP pointedly pointed it out in the thread title) is that he's going to jail, not prison. These two situations are only similar in the sense that you are locked up. Other than that, it could not be more different. I (unfortunately) have done time in jail. Twice. First time was 9 months, second time was 3 months. I have not been in prison, but know people who have, and have discussed in detail with them what the differences are. Some of those conversations were when I was in jail.
Firstly, and this is the most important thing: The OP probably knows this, but you jokers seem to not: no one tries to have gay sex/rape/whatever with you in jail. These things aren't even very common in prison, although they do exist, and some prisons are worse than others. But in jail - no.
Jails, like prisons, usually segregate people into different floors/wings based on severity of crime and length of stay. In jail, no one is there for an incredibly long time. The system will often have a cut-off in which a sentence of over a certain length of time becomes prison, and under that amount, jail. Where I'm from, the over/under is 2 years. And in jail, in many areas, you receive 2/3 off your sentence simply for not doing anything wrong while you are there. So the longest people stay is 8 months, not counting "dead time", which is time spent waiting for a trial if you did not get bail, or didn't have the money to post bail - in my case in my first offence, I served 9 months because I was sentenced "two years less a day" (to make it non-prison), and was in there for a month waiting for my trial.
So (sorry to be long-winded, but it's important to understand), if you are only with inmates that are serving 8 months max, no one is in there for killing people, and there aren't a bunch of psychos trying to buttf*ck you. There is very little violence (there can be some, but often for a good enough reason, and if you aren't looking for a fight, you won't get in one). Jail is filled with bored people who shoplifted, drove drunk, simple theft, selling/consuming drugs, crap like that. Even street bums who simply smash a store window when winter is coming, and then sit there and wait for the cops so they can go to jail for the winter. There aren't a bunch of violent nutters in there waiting to gang-rape people. Plus, you'll be segregated into a range with people serving similar time for similar crimes, generally. Troublemakers are kept in different wings.
Now, can you exercise? Here's the issue. Prison would be a LOT easier to exercise in, in many ways. They often have big yards, weight rooms, and paradoxically, more freedoms in certain ways. If you are doing many years, unless you are in a Supermax, you are given things that you don't get in jail. A TV in your room. A yard where you may be able to run around. Jail isn't like that. You get nothing. You're stuck in your little cell at night, and during the day, you are in a small dayroom where you can basically pace or do pushups in the corner. There's a common tv and some board games. The outdoor situation varies between jails, but in my case, it was being let outside 3x weekly for 15 minutes in a walled off area the size of a tennis court. No weights. Just a cement square. People stood around and smoked. You will almost definitely be stuck with calisthenics and that's about it. And if you do them too much, it will possibly bring too much attention on yourself and will just annoy people. You want to fit in and sit around and play chess, watch tv, pace, and nap on the floor with your little white towel as a pathetic pillow. That's what people do.
Sorry my post is long. If you find it interesting, great. If you don't, you shouldn't have read it, fool.
To the OP - good luck, and as famously said in Midnight Express: getchmis olsun - may it pass quickly.
