Again in terms of the details of the negotiations—and that's not my area of expertise—I think as a general principle people should know what they're working with. It doesn't matter what, whether it's asbestos or any other chemical or drug. It's always a good principle to have the least intrusive, most effective, with the fewest side effects, whether it's medication or something we use in different industrial processes—knowing what it is. That's part of the reason why there are declaration sheets in Canada for different materials used in industrial settings, as an example.
