We have had different companies from Canada in different countries suggest similar things, but suggestion is a long way from evidence. I appreciate your clarifying this, because until we're sure to have direct evidence, we have to be a little bit cautious.
My next question has to do with your sense of a study we can do. How effective do you think we actually could be in another country, away from our home country, investigating? We're going to be, to some degree, at the mercy of whoever is around us guiding us and assisting us. How long do you think that would take?
