My first job in TV was to present a documentary about alcohol. Part of that involved attending the dissection of an alcoholic's brain, and interviewing the pathologist during and after the operation.
The alcoholic concerned was, you will be happy to know, well and truly dead, and had been for quite some time.
We watched (and filmed. On PROPER film too, none of this video rubbish)as the skull was sawn open and the brain sliced. The single most memorable fact for me was the shrinkage of the brain, a shrivelling.
Over the past 23 days, I've visualised my own sober cerebellum expanding to fill the yawning spaces inside my skull, all the time awaiting great new insights, creativity and feats of memory.
