The chair is bolted to the floor near the back of a 12-ft. by 18-ft. room. You sit on a seat of cracked rubber secured by rows of copper tacks. Your ankles are strapped into half-moon-shaped foot cuffs lined with canvas. A 2-in.-wide greasy leather belt with 28 buckle holes and worn grooves where it has been pulled very tight many times is secured around your waist just above the hips. A cool metal cone encircles your head. You are now only moments away from death.
