I touched on that just now, but personally I do think it would be helpful to have more information. It's always the case, There's always a trade-off between the cost of getting that information and the value of the information. So, the question of how it would be used would be really important. There is still a lot that we don't know. We know an awful lot about obesity and being overweight and the causes of it, but we don't really have a very clear understanding, in Wales at least, of the point at which children start to become overweight. Although we know that overweight children tend to go on to become overweight adults, we don't know what proportion of them between school entry and later teenage years—what those changes are. So, it would help us to have some better understanding, which would help to direct some of our initiatives. I'd be generally supportive of the principle. We'll wait and see what comes out in the consultation, and it's something that we need to give thought to,  but we do have to trade off the additionality of what the information would give us with the cost of doing that, of course.
Okay. Thank you. We've got some questions now on healthy environments from Dawn Bowden.
Thank you, Chair. In the draft plan, some of the measures in there suggest legislating for restricting price promotions and banning energy drinks, and that sort of thing. Do you think that, if we go down that road, there's going to be time within this Assembly to introduce such legislation? And, if not, what do you think might be the timescale for such legislation?
It may well be that there are things in Wales that we might wish to legislate on, and you've mentioned two of them, and they're good examples. We would, obviously, need to undertake quite detailed consultation on those and, in a way, we need to mirror what's happening in England and in Scotland to some degree around the consultations they're having on energy drinks. We also need to influence the issues that are not devolved to us and we seek to do that. As to your question of legislative time, I'm not really in a position to answer that. What I could say is that legislation may well be one of the outcomes of the consultation. There may well be things that we wish to choose to legislate on. The timing of that will have to be subject to other pressures, and I come back to the point that legislation, of course, is one of the tools that we've got—we need to deploy them all.
