Traffic causes arthritis?

Here's a quick find - the New York Times today, described a research study that connects living near a highway with the development of rheumatoid arthritis in women.

Here's a good quote:

After controlling for age, cigarette smoking, oral contraceptive use and many other variables, researchers found that the women who lived within 55 yards of a large road had a 31 percent increased risk for rheumatoid arthritis compared with those living 220 or more yards away.

Don't anyone go calling their real estate agent (this is a bad time to sell, anyway). But it's another link in the chain connecting environmental toxins with autoimmune diseases.
