Urban air pollution

Anyone who has spent time in a traffic jam waiting to “get somewhere” can easily accept the premise that traffic can raise your blood pressure. If you don’t believe me, spend 30 minutes going 4 miles in Los Angeles or trying to go over the George Washington Bridge in New York at rush hour. A new study suggests that the creeping elevation of your blood pressure is not so much due to your fellow drivers but to pollutants in the air. Obviously, they haven’t driven in Jersey. What could they be thinking?
