A Particulate Matter

Mr. Wilber is urging all the athletes to wear specially designed masks over their noses and mouths from the minute they step foot in Beijing until they begin competing.

LOL.  Mr. Wilber is the US Olympic Commission's lead exercise physiologist.   
Such a huge slap to China's "dignitas" might be the only thing powerful enough to get the corrupt officials to do something about the environment.  Can just imagine the photos in the newspapers of athletes wearing masks.

The Chinese government really took a big gamble with these games.  Not sure its gonna pay off too well for them.
