The first `D' of Demographic. As somebody now who has had the experience, I would describe it, of being involved in many estimates procedures, over the last number of years, one trend that is clearly developing, and it's a matter that Minister McGrath dealt with, over the last number of years, is while we are seeing the size of our population grow, and we're seeing so many of the positive consequences of that, feeding through to our lives. We're also seeing a population that we expect to get older, because it's living for longer, which of course is incredibly positive. That has really important consequences then to the cost of our health services. And it has really important consequences for how we manage social protection expenditure. And it has already been acknowledged by the end of this decade, the many opportunities that I've talked about, behind that level of population growth, will have a really positive effect on our economy. But it does mean we'll need to be dealing with costs of between €8-9 billion more per year, which we'll need to account for, year by year, just to maintain the current level of service provision that we have. While we, and many of you, want that service provision to improve in the times ahead.
