That's what I need to find out; that's my problem.
Mr. Livingstone, you've had an involvement through UBC with the kind of issue we're talking about today. I'd like to ask you, what in your opinion is the most fragile part in this chain, based on your experience, when trying to provide life-saving drugs to those who need them in third-world countries? What is the most fragile part in that chain? We've heard about infrastructure that's lacking and about other things. I'd be interested in and would like to hear your viewpoint based on your experience at UBC with your colleagues, because I know you focus on this. That certainly is something that we in the Canadian Parliament should be focusing on as well.
