As for the question quoted, I wonder if it matters whether the individual is from North America or 'down under'? What about a North American in Australia and vice versa? Or is it food dependent (Vegemite is just plain nasty)? I think I've just found my next research project to scam the government out of another bazillion dollars. Thanks guys!
