I've just ticked the 'official' ones. I'm interested in all of the things on the poll, in some cases, e.g. History, possibly much more interested than I am in the subjects I 'officially' studied. I knew a long time ago that I ought to have studied Archaeology instead. I was also psychometrically tested and was told I'd have made a splendid Architect. It was all too late by then as I'd already taken my degree.
I was already interested in History long before I read any Tolkien, as my whole family are History buffs, but my interest in the English language did grow after reading Tolkien, or more accurately, reading
about Tolkien.
