Much sympathy re the cold, and I hope that it clears up and gets out of your lungs as soon as possible. (My parents are just back from holiday in China, and both have gumph in their lungs from overly well-conditioned hotel rooms, and their coughs are truly alarming. I have to restrain myself from running to demand that they go into hospital on the spot. Probably the fact that I code on the thoracic wards isn't doing much for my sang-froid.)

Take care, anyhow, and get better soon.
