Geoff was looking so well ...

 ... and now he is back in hospital. He was just getting back from the shops, when his head started streaming pus. It was pouring out like a tap. There was a small hole on the side of his scar, and that was what it was leaking from: no injury, it just seemed to split open. So he has had a scan and his doctor will decide what to do tomorrow. Geoff says he does not intend having another operation.
