Nicely written article. Even a non-scientist such as myself could understand the concepts you have so well explained. Thanks for that.

I do a lot of walking and can definitely confirm there are a lot of pollutants out there. Rarely is there a day that I’m not forced to breathe cigarette smoke in particular. I can see how location could play a big role as well. Our Kansas winds cause pollutants and allergens to do a lot of travelling thus impacting a large area.

Very interesting concept and article.
