How many couples sleep solo in a double bed?
A 2001 random telephone survey of 1,004 adults conducted by the National Sleep Foundation found that 12 percent of married Americans slept alone; a similar 2005 survey of 1,506 people found that number had jumped to 23 percent.
In addition, a March online survey of 1,408 couples conducted by the Sleep Council of England found that 1 in 4 people regularly retreats to a spare room or sofa to get a good night's sleep.
The preference for separate spaces has even begun to affect home design. According to the National Association of Home Builders, there's been a steady increase in the number of requests for "two-master bedroom" homes since 1990, prompting the organization to predict that by 2015, 60 percent of all custom upscale homes will be built with two "owner suites."
What do you think, is sleeping alone good or bad for marriage?
