“Dr Stanley, who sleeps separately from his wife, points out that historically we were never meant to share our beds.

He said the modern tradition of the marital bed only began with the industrial revolution, when people moving to overcrowded towns and cities found themselves short of living space.

Before the Victorian era it was not uncommon for married couples to sleep apart. In ancient Rome, the marital bed was a place for sexual congress but not for sleeping.” — Neil Stanley

“And then your alarm rings and screams at you to get up but you hurl it across the room in rage and sob to yourself that you can't possibly be expected to get out of bed and do something useful. And then you wander around the office feeling like you're moving through a forest of duvets, always a little too warm -- like your body has just decided that it's asleep in defiance of all the evidence. And everything is woolly and your brain doesn't work properly and nothing flows and it's all completely infuriating.” — Tom Coates
