I'm sick. I've been unwell for a week now having picked up an earache in Salalah that has turned into a fully fledged flu. I now have a sore ear, sore teeth (what the??), aching joints, dry and peeling lips, a cough, bunged up lungs, alternately blocked and runny nose, a throat just on the turn, a temperature and I'm feeling very, very tired. and lethargic.
