Why We Sleep
Sleep is something that we do almost every day and yet explore it only superficially. We either say “I should go to sleep” or “I wish I had slept longer”. Recently I read “Why We Sleep”. It’s an interesting book because it explores the topic in such depth. I learned that birds sleep on power lines and the birds on the right and the left of the group are sleeping with one eye open. Half of their brain is sleeping whilst the other half is awake. Half way through the sleep cycle they hop around and the other eye is opened and that half of the brain takes over. Sleep is a fascinating topic.
