Feeling sick in the winter time

The weather here in Utah just happens to match the way I'm feeling. It is snowy, cold, and sloshy. although I don't feel snowy or sloshy, I do feel sick. I woke up this morning with a pretty bad soar throat. Being the trooper I am, I went to work and decided to stick it out. However, I arrived at work and felt awful and decided to go home early. Now I'm in my robe sitting on my couch watching Gilmore Girls and seriously considering calling in sick.
