One of the nice things about writing this ‘Blog is that, even on the quietest days, there’s a fair chance that my dad will drop by, so that PooterGeek will get one hit at least. Some of you probably know that he has had radiotherapy this year. Yesterday he was told that he now seems to be clear of the cancer that this was intended to treat. He must take credit for nudging the NHS at first, but they did a good job. And good on you also dad, for putting up with the misery of being a target for ionizing radiation.
