I have never found a rusty snake

Terry Pratchett recently announced that he had early onset Alzheimer’s which I and others with various degrees of distress blogged at the time. He has just announced a major grant to Alzheimer’s Research and his speech is a delight. He talks about the way his web site was inundated following his announcement. To quote: Some of them wanted to sell me snake oil and I’m not necessarily going to dismiss all of these, as I have never found a rusty snake. That exemplifies the ability of Pratchett to link and connect the disconnected, to make important statements with humour. Long may he stay writing. Hat tip to Neurophilosophy for the link.
