I have recently been re-reading Georges Perec's Life: A User's Manual, and remembered an article by Ian Jack in the Guardian quite some time ago. In it he points out that Perec once attempted to keep a list of everything he'd eaten over the course of a year. (It was a frighteningly diverse and at times curdling account).
After my fourth visit to the hygienist in twelve months (costs me £40 a pop for the privilege each time) I realise that I really need to cut down on chocolate, so, in an effort to curb my cocoa addiction and improve my general intake of food, I'm going to attempt the same thing as Perec, but for a week only. Unlike Tim Stretton, I'm not much of a list-maker/listmaker/list maker, but have a notebook for this very task. I'll post the results on here next Friday.
