Ever been told you got out of bed the wrong side?
A new survey has found that there may actually be some scientific truth to that.
Bed manufacturer Sealy UK surveyed 1,000 people and found that those who slept on the right side of the bed were seven per cent more likely to wake up grumpier than those who slept on the left side. They were also three per cent more likely to dislike their job.
Those who slept on the left side were nearly 10 per cent more likely to have a "good outlook" on life, according to the study.
An expert at Sealy UK said: " While the margins are small, the research certainly highlights an interesting trend."
A similar survey of 3,000 adults carried out in 2011 had similar results.
