Black Lung Disease

People riding the subway are exposed to every germ known to mankind! I am not familiar with anything called "subway disease" but you can rest assrued if there's something going aroung, it's on the subway!

I'm going to go out on a limb and just say no. From what I know of subways, they are driven by electric motors. Anyway, coal miners, at one time, were in environments where the dust was so thick, you couldn't see ten feet ahead.
