Mr. Davies, you had me right up until about this point, because your argument implies that, when a person is 18, everything is okay. Yet we heard testimony from physicians, from doctors, who told us that at 25 the brain is still maturing and damage can still be done. I'm a little puzzled as to why or whether you in fact are saying the age restriction really shouldn't apply. As I said, if it's unhealthy for an 18-year-old, or for someone who's 19 or 20, according to the testimony, why would we be so adamant not to allow the 17-year-olds to get hold of this stuff?
There's a little bit of a conflict there. Do you want to take an opportunity to try to explain that to me? I'm having some trouble with that one.
