How about sleep gyms?

The odd thing is that every week there are loads of stories saying how much we need sleep, with the implication being that we don't get enough. Except sleep doesn't cost anything. It's not as if you need a lot of space or equipment for sleeping. So why do we starve ourselves of sleep?

I would like to turn the tide. Rather than having gyms for running around to improve our health, there should be places to go for a half-hour kip. Rather than lots of sweating middle managers on treadmills, looking glazed and martyred, there could be comfortable, softly-lit sleep gyms, where people could get under the blanket for a decent stretch. Which would make you happier and healthier?
