Something new to worry about

Biker's Lung.

If you read the press release from the European Lung Foundation, however, it states that the study only looked at ten people: five bicycle commuters, five pedestrian commuters.

The results make sense though. I'd like to know how much of the higher black carbon levels is due to the proximity of the bicyclists to the cars (opposed to the pedestrians), and how much is due to the bicycle commuters breathing deeper while riding.

And were the black carbon levels exhibited by the bicycle commuters dangerous, or close to dangerous?

I also often wonder about the healthiness of breathing in the road salt mixture when riding on dry days in winter, after a snowfall.

I also often wonder about the healthiness of worrying about stuff like this all of the time.

That may cause more health problems than the deadly black carbon urban cyclist lung.

And that is a shame.
