I haven't (as far as I know) tested my ability to eat arsenic in very small quantities, but I understand it's normal, for small values of "very small". And avoiding people I wouldn't, for example, buy sausages that I knew had had a whole person fall into the mincing machine even if it was accidental. Maybe I should have ticked "Trivial" instead. On the other hand, given a sufficiently dire emergency (http://en.wikipedia.org/wiki/Uruguayan_Air_Force_Flight_571#Food_and_water) where the people in question are already dead, I think I'd eat them. I'm not sure I could cope with the "let's draw lots to see who in the lifeboat gets killed because otherwise we'll all starve" (http://books.google.co.uk/books?id=KvB6NPbSByAC&pg=PA251&lpg=PA251&dq=lifeboat+cannibalism&source=web&ots=w9xOm5k8yh&sig=IhAPoGelQnw9RgW2ATTkQ_iDpGw&hl=en&sa=X&oi=book_result&resnum=10&ct=result#PPA249,M1) system though.
