Thank you to a couple of readers who kindly told me that I'd confused my protons and my neutrons, but didn't call me the blithering idiot I clearly am. I would blame the demon drink, but for the fact that I was stone cold sober when I wrote that bit. Huge embarrassment. I asked Julie to whip me with birch twigs to help me purge my mistake, but she reckoned that it would be no punishment, not with all the kissing better afterwards.......
