Speaking of stupid, I have a renewed disrespect for smoking. I experienced a years worth of smoke in my lungs in less than a minute and let me tell you, smoke and lungs don't mix, and there is a reason firemen use a fancy oxygen mask and not just a shirt pulled up over their nose and mouth. I was hacking for about a half hour after my jog through the black cloud, and I still have black boogers.
Attention all people who sleep in your underwear: its a pretty good idea to keep some pants and a shirt within reach just in case your house catches on fire and you have to run outside in the middle of the day with the entire neighborhood staring, complete with media crews and helicopters over head. But, I guess it's better alive in your skivvies than dead fully clothed.
