" When humans work, they frequently become unaware of their own body, their own senses, are surprised to find that their wrists ache or their backs are sore or their friend has left the building. It's as close to an out-of-body experience as can be achieved short of fifty volts, a circle of warding, a pigeon's claw cut from an albino female of purest white feathers, or a lot of mushrooms. "
