“Prisoner 1027820 is treated in many ways like any other inmate at the Lovelock Correctional Center in Nevada: He gets the same standard issue blue uniform. He shares a bunk, toilet, and sink with a cellmate. He rises around 6:30 a.m., eats an early breakfast—he likes cold cereal, with a muffin and fruit—then heads to his work shift….He toils in the prison gym, cleaning equipment, and mopping floors, four days a week. Like many older inmates, he contends with age and ailments, including bad knees, and he works out on weight machines regularly to stay fit. He also coaches prison sports teams, umpires games, and recently became prison softball league commissioner.”
