But I have written about diets and calories and all the paraphernalia about losing weight. I made so many references in one book - I think it was A Single to Rome - that my editor asked me if the main character had a weight problem as all she seemed to think about were calories.
What can I say? I don't smoke and have a tendency to put on weight, and my writing reflects my preoccupations. My characters are often stroking and touching things which reflects my own tactile habits, but rarely fuss about what they're wearing (unless it's a concern that they've got it wrong). We had a discussion in class about using the five senses, and many of us (including me) said they had a poor sense of smell so rarely included that, whereas for others it was as important as the visuals.
I do a certain amount of manipulation so my characters have habits and characteristics other than mine - more have had straight hair than curly, although I'm hazy about what using straighteners implies, so try to avoid too much hair description - but I'm sure my real concerns and preoccupations shine through. When I read Caitlin Moran, and in particular her recent book How to be a Woman, I often feel like saying: not all women suffer from cystitis. That's you, not me.
James Joyce once wrote that all fiction is autobiographical fantasy, and perhaps there's more autobiography in fiction than many of us would care to reveal. But I think we just can't help ourselves.
