I used to believe that if someone did something very bad, and got sent to prison for like 150 years or so, that they would have to finish their prison term even if they died in prison. That means their dead body would be just sitting there, in the cell for 150 years, stinking up the prison. I also thought you were forced to eat rat turds in prison, it's what my mother told me.
