One of the craziest things I sometimes see is someone sitting in a car with the engine running in front of health food store, while waiting for someone else to do their shopping there.http://www.eurekalert.org/pub_releases/2015-03/acoc-apc030315.php

People living in areas with more air pollution face a greater risk of carotid artery stenosis, a narrowing of the arteries that supply blood to the brain, according to research scheduled for presentation at the American College of Cardiology's 64th Annual Scientific Session in San Diego. Carotid artery stenosis, which results when fatty substances build up in the arteries in the neck, is associated with more than half of the strokes that occur in the United States each year.
Several recent studies have linked air pollution with cardiovascular problems, but most have focused on effects in the heart and surrounding arteries. This new study is the first to examine effects in the arteries in the head and neck, shedding light on how air pollution might increase the risk of strokes that deprive the brain of oxygen. Such strokes are among the leading causes of death in the United States.
"Our study adds to the growing body of evidence that air pollution is a significant risk factor for cardiovascular disease," said Jonathan D. Newman, M.D., M.P.H., a cardiologist at NYU Langone Medical Center and the study's lead author. "It shows that a person's cardiovascular risk is not only associated with their genes, health behaviors and lifestyle choices, it also depends to some extent on the world we live in and the air we breathe."
