SLEEP, in the UK, is a problem. It’s something we moan about. We’re not getting enough. We wake up in the night, worrying about family issues, money, whether we should delete that drunken Facebook post from last night, or what to do about the North Korea problem. This concern over sleep deprivation is a peculiarly British and North American problem. A report last year found that 38 per cent of us said that we felt we were not getting enough sleep – compare with 11 per cent of Chinese and 7 per cent of Indians who report this feeling.http://www.heraldscotland.com/news/16079054.And_____sleep__How_we_became_an_insomniac_nation/
