(Dujon) It would seem to be a good day to hang out the washing around here. I doubt if you'll get a true 47°C though Melbourne might. The cool change could be quite something. I'll keep an eye on it.
As a special not-birthday treat, my wife took me to the optometrists. He (the optometrist, not my wife) said my prescription had changed "a little bit", but when I compared the two sets of numbers I could detect no correlation between them whatsoever.
