You need your spouse in your bed.

In the New York Times Sunday morning Bruce Feiler wrote an interesting article about couples who sleep together. His research showed that nearly one in four American couples sleep in separate bedrooms or beds, the National Sleep Foundation reported in a 2005 survey. Recent studies in England and Japan have found similar results. And the National Association of Home Builders says it expects 60 percent of custom homes to have dual master bedrooms by 2015.
