Whilst attending the unveiling of a new memorial in Duthie Park, Aberdeen to the scientists who in 1922 developed the first medically useable insulin, I got my chance to say thank you to one of them – native of Aberdeen and later, Professor of Physiology at the University of Toronto, John James Rickard Macleod. (Incidentally, that’s my insulin pen in my hand, not a vape I’m offering him.)

The following day on a return visit to the park, a sudden bout of hypoglycaemia in close proximity to Macleod’s statue resulted in a letter about his work in the Financial Times…ah well, as they say, every cloud….
