I don't have time for another question, but I do want to say that there are a number of measures that are moving forward in terms of dealing with those challenges, including the option of perhaps deferring, keeping that workforce going. So I think that to take one very difficult policy decision, but an important policy decision, and isolate it from all the other issues is perhaps not really looking at the whole demographic challenge that we're going to face and how we're going to deal with it.
Thank you.
