Accents are funny things you often can't hear in yourself but can pass on. I remember a Japanese girl in NZ asking me what currency we use in Britain. When she repeated 'pound' back to me, I could hear a Gloucestershire accent...
Anyways, a thing I've learnt today is the word 'perfusion'. A less interesting but, unfortunately, more directly applicable thing, is the New York 11 (a sugar contract).
