I would say that it's really within the last 10 years that in many regions we've hit the wall in terms of our built infrastructure. One of the other pieces we could get into, if we have the time, is all these predictions about what the future's going to look like and what infrastructure build we need to put in place. They're all based on a business-as-usual case. As we all know, business will not be as usual on a go-forward basis. We're looking at a future that's going to be characterized by electric vehicles and smart grids and so on. Not only do we have a challenge in terms of renewing today's workforce, we know that tomorrow's workforce is going to have to be even more skilled than the one we have today.
