In the mid 1970s I spent a year working at a clinic in what was then a small spa town, Leukerbad, high above the Rhone Valley in Valais Switzerland. There were about 10 of us and we came from other countries in Europe, Canada and Australia, none of us had met before. I sent some photos home to my parents and my father took them in to the tax office in London where he worked, to show his colleagues. One of his colleagues was surprised to recognise his niece, who lived in Australia, in one of the pictures.
