That frustrates doctors no end, because while COPD isn't curable, it's largely preventable. Although genes play a role in the disease, about 85% of all cases in the U.S. are triggered by smoking. When cells are exposed to toxic substances for prolonged periods, they tend to become inflamed and swollen. In COPD, cells lining the lungs swell to a point at which they restrict the flow of air. "It's like a sunburn of the air passages," says Dr. Thomas Petty, a pulmonologist at the University of Colorado Health Sciences Center in Denver and at Chicago's Rush...

In reality, it tends to affect the middle class more than anyone else, especially those in the suburbs with more than one car.

...tend to think of prefab housing as one of those products of the industrial age, like the videophone, that the world has not exactly rushed to embrace. Americans have no problem with mass-produced cars and mass-produced coffee. But show them a house that has been manufactured in parts in a factory, then trucked to the building site for final assembly, and they start to flinch. The prejudice against prefab may date to the earliest human notions about home. Say what you will about caves, they were definitely not factory made...
