Even those who use it occasionally are 6 times more likely to get sick? Not for me. I've weak lungs (since childhood) and I just can't take the chance.
This is a another great reason to celebrate the American car culture and the freedom (and health and wellness) that it brings with it! To all you "environmentalists" who hate cars, I ain't gonna risk getting a terrible upper respiratory infection just to please you.

To hell with all those who would force their fascist transportation on everyone!
