Thanks very much. Well, what we have seen is an increase of 40 per cent in terms of demand over the past five years when it comes to HRT. And the real problem is that manufacturers haven't kept pace with that demand. So, we are working with the UK Government, who, of course, is responsible for procuring this on our behalf, and, obviously, people are being advised to perhaps go to alternatives that are available. I'll look at that issue in relation to surgical menopause; it's not an issue that I've come across before, but we'll certainly ask officials to take a look at that as well.
