Not really news to me, but it's reassuring to read confirmation of what you already believe: needing eight hours of sleep is a myth:
And it's become an increasingly common sentiment that too much work and stress and missing out on our eight hours is the modern plague. But the good news, says Prof Jim Horne, director of Loughborough University's Sleep Research Centre, is that we don't need eight hours at all. "It's nonsense. It's like saying everybody should have size eight shoes, or be five foot eight inches. "There is a normal distribution – the average sleep length is seven, seven and a quarter hours."
