I am Planta: On the Line. This is THECOMMENTARY.CA.
Jeff Warren is a former producer at CBC Radio’s The Current. His two hour-long Ideas documentary on the science of sleep became the basis for his new book The Head Trip: Adventures on the Wheel of Consciousness. The book, published by Random House and retailing for $34.95, looks at the 12 distinct, natural states of consciousness we experience in a 24-hour day. We are apparently not merely awake, or asleep, or dreaming. Please welcome to the Planta: On the Line program, Jeff Warren; Good morning, Mr. Warren.
