Glad to see you're back at work! Shame about the cold in London... one of the things I don't miss about it. Anyway, I didn't comment about the 'Joans', but I have to say that I like these real-life posts much better. Phrases such as 'cerebro-spinal fluid is the liquid that your brain and spinal column float in, and should not be outside the body at all' are pure genius - they are informative, but also just plain brilliant.
