Does a happy marriage mean separate beds?

WASHINGTON, D.C. - -  
One in four american couples sleep separately, according to the national sleep foundation..
Doctor David Luterman, medical director at Baylor's sleep center expects that number to grow.
 "The husband will snore very loudly and the wife will ask him to go get it fixed. finally the wife says, 'i can't take this anymore.' she's not sleeping. she's moved out of the room. he gets serious; he comes in," Luterman said.
Even mattress makers, capitalizing on the sleep separation, are producing more dual adjustable beds.
"In the past, we'd seen that this skewed for older couples but we are seeing younger and younger married couples coming in.. in our busy lifestyles, sleep is important," Christine Cook, president of Sleep Experts said.
