Thank you.
The last point, if I have time, concerns the nurses. Given that we're going into a period of massive deficits--that's the reality, meritorious and virtuous as all of the proposals are--there's going to have to be a business case for everything we ask for, let's face it. We're going to have to show where there's an economic benefit to these proposals. With nurses, the advanced role of nurses in the health care system, or expanding the role the nurses can play in the health care system, has the research to date shown that there's a material cost benefit to expanding and enhancing what tasks and duties nurses play within our system?
