Morning.
We just spotted this truly eye-opening BBC story about sleep and, as sleep is a bit of a hot topic (and much-missed state) on MN, we thought we'd share it with you.
Apparently, sleeping for eight hours is unnatural, and 'segmented sleep' - sleeping for a bit, waking up for a bit, then sleeping for a bit more - is much more normal and, in times past, was the accepted norm.
So, basically, lying awake could actually be good for you.
Oh, and fabulous quote from the BBC story: 'one doctor's manual from 16th Century France even advised couples that the best time to conceive was not at the end of a long day's labour but "after the first sleep", when "they have more enjoyment" and "do it better".' 
So, what's your view? How much sleep do you reckon you get on an average night? Do you worry about not getting enough sleep - and does this story reassure you? Or do you still yearn for the blessed relief of a full eight-hour stretch? Please do tell...
