My Respiratory System Hurts

Yecch! Particularly smoggy day today, and unfortunately, it never got any better. In fact, just the opposite occurred. You see, the smog is heaviest in the morning, because throughout the day the UV rays from the sun help break apart the smog, and so by the end of the day, usually, the sky is somewhat clearer....with heavy, heavy emphasis on usually here.  

For some reason, today started out extremely foggy...and only got more so as the day progressed. Why did the laws of nature as they were taught to me in Earth Environment randomly reverse themselves this particular Tuesday? I wish I could tell you. All I know is that by the time today wrapped up, the smog had gotten so thick, I could practically feel it with every breath that I took. 

To my family - I have a new item to add to my Christmas wish-list. This year, I'd like a chisel - to chip away the layer of filth that will have built up in my lungs by the time I return home.
