NBC Covers Decreased Air Pollution Leading to Longer Life

Sometime in the middle of the night last night, Danny told us that a drop in air pollution has linked to longer lifespans. Of course, it seems like this would be a no-brainer, but it had actually never been proved (proven?) by science. But even NBC has run with this story, and when Brian Williams says something, you know it's the gospel truth.
So, there you have it. Science + Brian Williams = infallibility. takepart with the American Lung Association's Clean Air Standards and let's live even longer!
