Actuaries will have to take into account projections of the possible impact. I do not know whether they have decided on the projections. The extent to which they need to take them into account will depend on the type of industry in question. There are some occupations in which obesity is unlikely to be a problem. However, other occupations might need to take into account issues related to obesity. This is not a one-size-fits-all issue. It is about getting trustees in particular areas and particular occupations to be able to project what sort of longevity members of particular schemes might have and therefore what the adequacy of funding will be. One of the issues that they will consider when they make their calculations is the projections offered by the Office of National Statistics, which will deal with the sorts of points raised by the hon. Gentleman.
