Britain’s newspapers have been full of predictions this week about 2012, when London will host the Olympics. There is a sense both of excitement over potential success and trepidation over potential failure, both on and off the sporting field. It is too early to predict with any confidence whether the London Games will be a success or not, but one thing I can predict, with utmost confidence, is that by 2012 many more of us will be defined as mentally ill.
