News that Konami's Dance Dance Revolution burns calories and is healthy for you aren't new. You don't really need scientific studies to support the obvious, especially given all the sweaty DDR players one can run into on a trip to the arcade. What's news though is that schools have now incorporated the tub-thumping game into their P.E. classes.

You know what? The kids love it.

The New York Times reports that at least several hundred schools in at least 10 states are now using Dance Dance Revolution as a regular part of their physical education curriculum. It is reported that based on plans, more than 1,500 schools are expected to be using the game by the end of this decade.

The system, including the TV and the game console, only costs each school around US$ 500, but most schools spend up to US$ 800 for more robust mats.

Linda M. Carson, a professor at West Virginia University's School of Physical Education, and director of West Virginia's Motor Development Center passed by an arcade. "There were all these kids dancing and sweating and actually standing in line and paying money to be physically active. And they were drinking water, not soda. It was a physical educator’s dream."

What's nice about this is that unlike other things asked of you during P.E., you don't have to be good in DDR to get a work out.

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.

The New York Times report also said that there may be even more cases like this which aren't revealed because of the negative perception towards sleeping separately. The matter can be a sensitive issue and some couples don't want to talk about it.

What's important, says the report, is that conjugal bliss and comfort is preserved, and if sleeping apart is the best avenue to achieve it, there's nothing wrong with it.
