And I'd urge you to ask the chief medical officer to look at this. You say it might be something for the future, but when we're fighting coronavirus, the future is now in a way. What's going to happen with the pattern of the disease in Wales over the coming months can be affected by decisions that are taken now.

I've spent much of the past three months pushing for the best possible protection for front-line staff. You mentioned them, of course. I still need to do that. Maybe you could comment on reports of out-of-date PPE still being in use—masks expired in 2008 being seen by nurses with stickers underneath saying 'expiry 2016'. I'd be grateful for a copy of guidance on the process that's followed to decide when expired PPE is fit for re-issue.

Again, to finish, on that issue of the public wearing of masks—a homemade mask is much better than nothing. Of course, it means there's no impact then on PPE stock for key workers. No real cost either, so issues of equality are addressed in that. Worldwide, there are community schemes making masks, including groups in Wales. This is my mask, actually. This has travelled across the world. It was made by a friend in the United States—part of a community group making masks to give to others. Will you support a mask Cymru initiative urging more people to get involved in making masks, sharing simple templates and so on? This is something we can all do, bonding us as communities. We can even have competitions: who can make the best looking masks and that kind of thing. It contributes to the normalisation of the wearing of face coverings, and just perhaps, if the growing evidence is right, as I believe it is, it could save lives, too.
