Nevertheless, if we can tidy away and assume away that problem, there are other difficulties, not least of all is the fact that I'm not sure that we're necessarily confronting the true problem that we face with dental hygiene. I was on a train several years ago, and I was horrified to see a couple of young parents feeding a toddler Coca-Cola through one of those baby bottles with the latex teat. Now, I just can't imagine what that would do to a child and their teeth. I'm pleased to say that the train was in Australia, where that and other types of criminal activity are part of the national story. But if we're honest with ourselves, we have very similar problems here in New Zealand. There are a lot of enormous difficulties placed on children by a lack of parental responsibility, and so another criticism that people might put on to this initiative is that unless it's allied with a serious effort to get better parenting, then it's not going to solve some of the worst dental hygiene and health problems that we have here in New Zealand.
