The Riddle of Sleep
Narrated by Anthony Clare
Do you have trouble getting to sleep at night? Spare a thought for Leslie Gamble. He claims he hasn't slept for 11 years.
On the other hand
Joyce Hannon always feels incredibly tired. Many times a day she simply falls asleep whatever she happens to be doing. Joyce has narcolepsy - a quarter of a million Americans have it - but the odds are you won't have heard of it, because the world of sleep is shrouded in ignorance. Yet it's a world in which we spend a third of our lives.
