Yesterday was really windy. Lots of bikes fell over, including mine. I thought my sheets, hung to dry outside my apartment window, had blown away. I searched for them around the building. I eventually found them — in my closet. I got a piece of dirt in my eye that I noticed for several hours. It was my first significant bad encounter with Beijing air this time around (since August). I was in Beijing last fall, too, and then the dirty air really bothered me. I felt better after I got an air filter for my apartment.
When I was a freshman at Caltech, Richard Feynman came to our dorm for dinner. I asked the first question: “What do you think of the air?” He looked at me as if it was a stupid question. I think his answer was, “You get used to it.” After living in Beijing last year, I said over and over I liked everything except the air. Now I find it hard to complain about the air. In my apartment I have one big air filter per room that runs constantly; they are quiet and turn red if the air is dirty. They hardly ever turn red. Last year, after a week without dusting, you could write “lung cancer” in the fine black dust that had accumulated. Now it isn’t there. Through my window the visibility is usually pretty good; I can see the lights of buildings in the distance.
Yesterday someone told me Beijing air has gotten much much better. “Ten years ago your hair would get filthy” from coal dust, he said. The hutongs had coal-burning heaters. Now they are gone. Measures of air quality have even improved since last year, I think he said. I met someone recently arrived who was bothered by the air but she felt much better after I gave her an air filter.
Overall, I think four things have changed: 1. The air in my apartment, where I spend most of my time, is much better (compared to unfiltered). 2. Outside air is somewhat better. 3. Due to fermented foods, my overall health is better. 4. Due to learning about hormesis, I don’t worry about a small amount of air pollution.
