My area of expertise is really health care, so I don't know that I can answer all of your question. In terms of health care budget, there's a lot of evidence that would suggest the money we're spending at the moment isn't getting us the value for money that you would think it should.
In terms of the age of the population, there is a considerable debate about what impact that will actually have on health care costs. There is a suggestion that the bulk of health care costs occur in the last year or two of life—I believe 80% of an individual's health care expenditure occurs in the individual's last 18 months. Set against that is an actual fact that the boom generation that everyone's concerned about could actually be the healthiest generation we've seen. There's certainly evidence that the generation that's following it may not be as healthy, so whether or not your question may be one generation misplaced is another matter.
I would answer that question by saying, first, I think we can do better with the money we're spending at the moment. People talk about bending the curve of health care costs, and it may only be that 1% or 2% of GDP might make a huge difference. We certainly don't get the performance value back for the level of expenditure compared with what the European and the OECD indicators would suggest it should.
