A survey by construction companies and architects recently revealed that as couples move in, more and more of them are asking to gave separate rooms built. It seems a little strange considering that most of them are married, but it's true.

The New York times set out to find out why this is happening and the answer turned out funny at first. It wasn't the sex or rifts between lovers- it was snoring.

It may sound like a trivial issue, but the fact is that experts are predicting that by 2015, more than 60 percent of new homes built will have two master bedrooms. Such projects can run the cost of more than a thousand dollars, but couples say there's no substitute for good sleep.

And it goes beyond snoring, according to interviews with couples and sociologists. Irregular sleeping habits, emailing late in the night, sleep-talking and insomnia are among the causes of bedroom separation. Mrs. Lana Pepper recalls the years of sleeplessness with her husband who had plenty of bedroom quirks.

He cannot have his feet tucked into any of the covers; I have to have them tucked in. So I took all the linens and split them with scissors. Then I finished the edge so that half of the sheet would tuck under and the other half he could kick out.
