Yes. I know the way that StatsCan handles this when they're dealing with population projections, which are notoriously wrong over the long term, is that they have a high, a medium, and a low estimate as to what population trends will be.
The chief actuary, I believe, although I stand to be corrected on this, does something similar when he's attempting to project out with relation to the funding needs of the Canada Pension Plan and so on. Would that perhaps be a way of resolving the problems, and we're getting beyond the five-year horizon...?
