Do you have anything to say about numbers? I know that there—of course there was homelessness 40 years ago, and it would have been more prevalent in London—of course. But the actual numbers of people that you can see sleeping on the streets now is much greater than anything I've ever experienced before, and I think it's down to the reasons that you've described there. Do you have any evidence to suggest that the volume of homelessness is a much bigger problem than it was, say, 40 years ago?
