My arms are feeling better now. Still a bit sore, but much better. I got some rub in ibuprofen yesterday which has really worked well. The only side effect is that the commercial stuff is called Ibuleve, and I have been humming 'I believe' by the Bachelors ever since. Oh dear. However it is worth it.
I am glad, heartily glad, that I am not flying anywhere with the dust cloud from Iceland.
Poor people sitting in airports.
