Thanks for the kind remarks and information. I’ve been remarkably short sighted since I was 10 but I now believe I am developing (fairly) early onset macular degeneration, which is distinctly unhelpful. As for the arthritis, well that just confirms my aversion to doctors – as soon as I see one (about every fifteen years or so) to ask about a problem it immediately becomes dramatically worse. If I don’t acknowledge them the problems stay peripheral. Obviously this isn’t a remotely logical proposition but, for me, (basically) doctors create health issues!
I suppose I’ll have to invent my own idiosyncratic abbreviation system to account for “Infanterie-Regiment Herzog Friedrich Wilhelm von Braunschweig (Ostfriesisches) Nr. 78” in 12 characters!
