On the human resources side, in seven or ten years from now, I understand that 30% of your workforce is going to be retiring. Therefore, if in fact we're going to continue to do all those other things we need to do, how important is the human resource side of the equation to your production, and to our competitiveness and productivity? What are some of the things you think we need to do? I know you've touched on it, but what specifically do you think we need to do with regard to human resources and skills?
