I seem to have some sort of head cold. At least, let's all hope it's a head cold, because when you haven't got Dr. Google on 24-hour standby, you're apt to start flicking through the "Illnesses and Diseases" section of the Lonely Planet Southeast Asia instead and finding that why yes, you do have a sore throat, body aches, and small itchy spots on the inside of your elbow, so quite obviously you have Japenese Encephalitis. And malaria. And dengue fever. And SARS.
