A: 2 master bedrooms

The marital bed, once a symbol of holy matrimony, may someday be a relic of the past. Why? Nearly 25% of married couples in the United States now sleep in separate beds, according to the National Sleep Foundation. Separate sleeping arrangements are so popular that the National Association of Home Builders says it expects 60% of custom homes to have dual master bedrooms by this year. Angelina Jolie and Brad Pitt often sleep in separate rooms, says a former bodyguard. As Barbara Tober, the former chairwoman of the Museum of Arts and Design, told The New York Times recently, “Not that we don’t love each other, but at a certain point you just want your own room.”
