Professor David Albert Jones:

You can speculate as to the reason, but I do not know of an example where they have not gone up. That is also true in places like Switzerland, the Netherlands, or Oregon, which have had more than 20 years of this. The numbers are still going up. I do not think that is a backlog. I think that is a culture shift. I think it came in last year in New Zealand, so it is difficult to know where New Zealand will be in ten or 20 years. If you want to look at where we might be, you should look at places that have had it for longer. I also question the notion that you could restrict these things. They have a momentum and logic of their own. If you say you will allow it for a certain type of person, or if you can take it yourself, then why not also allow a doctor to do it? There will be pressure.
