Sleep Deprivation en Sleep <p>03/01/2014 - Birds do it, bees do it...yet science still can't answer the basic question: why do we sleep?&nbsp; Every creature on the planet sleeps - from giant humpback whales to teeny fruit flies.&nbsp; What does it do for us, and what happens when we go without it?&nbsp; We take a peek at iguanas sleeping with one eye open, get in bed with a pair of sleep-deprived new parents, and eavesdrop on the uneasy dreams of rats.</p><p></p> Mon, 24 Feb 2014 17:14:12 +0000 Sue Ginn 15391 at Sleep
