I don't know about a useful exercise. First sip of tea of the morning and it scared the hell out of me. Rappaport is a good blogger and I have loosely followed what he's been writing but it is still only an informed opinion and Rappaport isn't a doctor so this is veering dangerously close to fear porn considering that none of us know the truth of what is happening, and this is what I am telling myself to feel somewhat calmer....
