In the late 80s, I delivered the Washington Post as a 9 year old — I skimmed the articles daily and one about local BBS sites with phone numbers fascinated me.

I called the numbers and heard weird noises. I was beyond intrigued and had to understand this new world.

8 months saving for a Commodore 64, 6 months saving for a 300 baud modem and I was hooked!

I was curious about this too, basically they're just filtering air as they go and counting it as negative emissions:

If I understand this correctly, could wearing nose clips and only mouth breathing be an effective strategy to reduce impact?

That seems like the hypothesis they suggest. Interesting implications.

All the people who were made fun of in middle school for being a 'mouth breather' will have the last laugh.

'mouth breathing' is actually really bad for you.

How so?

Your nasal passages include structures called "conchae" which, among other purposes, secrete mucus to capture small and potentially disease-carrying particles from incoming air. [1] It's not a perfect defense, of course, but better to have it than not - and when you breathe through your mouth, you don't get the benefit.

can't laugh when you are breathing with your mouth, my friend :)
