I took what is being perceived as the cliche “sick day after coming back from Las Vegas” today, but in fact, I am really not feeling great. I think it’s a combination of the lack of sleep and all of the smoke in that city, not to mention the travel that did me in. Whether it is allergies or a cold that is developing (or just irriation of some kind) I don’t know, but it has more or less wiped me out.
