Why aren't you wearing a mask while cycling/walking, especially in cities?
>use the London tube for a week
>my nose snot is black at the end of each day
Apparently this is common and the explanation is the amount of iron in the air (from all the decelerating of the trains). This got me thinking about all the shit we breathe in during the day that is not as apparent as the black snot you get from iron in the tube. For me wearing a mask is a no brainer. Desert dwellers wore veils over their faces for millenia so they won't breathe in sand. You should wear one as well to not breathe in metals, rubber tyre particles, and other fine particulates.
