I also want to make note during this, while we are talking about biosecurity, that one of the things I think about is that as we closed the border, a lot of people were redeployed into other parts of MPI or redeployed into other jobs. I often think about that, as we are reopening the borders now, it's going to be ever-important that we make sure that those people are deployed back to the borders, where they need to be, because, as more and more passengers start to come in—and it's really important they do—we're going to find ourselves in a space where we're going to need those people back on the borders again and looking after us.
