Experience: I spent 29 years in solitary confinement | Robert King | Life and style | The Guardian:
It was a dimly lit box, 9ft by 6ft, with bars at the front facing on to the bare cement walls of a long corridor. Inside was a narrow bed, a toilet, a fixed table and chair, and an air vent set into the back wall.
Some days I would pace up and down and from left to right for hours, counting to myself. I learned to know every inch of the cell. Maybe I looked crazy walking back and forth like some trapped animal, but I had no choice – I needed to feel in control of my space.
At times I felt an anguish that is hard to put into words. To live 24/7 in a box, year after year, without the possibility of parole, probation or the suspension of sentence is a terrible thing to endure.
