In reply to Andy Johnson:
After 25 questions it had me as broadly from north west England. After the full 90-odd questions it had me from southern Lancashire (the old county boundary, not the new).
As I was born in St Helens but have lived in south west England for a total of ten years or so out of my 55, and have mixed with people from all over the place, that's not a bad guess. You can tell a lot about someone if they ask you for a barmcake.
