One of the joys of computer search is when it throws up strange stuff that seems much more interesting than the topic you are concerned with. Best one today is 'Sword swallowing and its side effects', an article in the British Medical Journal. I particularly like its reference to a sympton known as a 'sword throat'. Recovering from flu, I reckon that's what I have right now.
I'm a little puzzled about how this article appeared in my search for research on the effectiveness of financial advice. Perhaps sword swallowing and financial advice are both forms of trickery and illusion.
