The final point is around personal protective equipment (PPE). The one thing I would say is that PPE is good if it's used properly, but, actually, PPE is a risk if it's not used properly, and one of the biggest debates that you'll hear happening up and down the country at the moment is around face masks and that, actually, the vast majority of people who are wearing them are wearing them wrong. It means they are increasing the risk, because if they're wearing them wrong, they give themselves a false sense of confidence, but also, if they're touching their face more because they're wearing a mask, they're actually increasing the risk to themselves rather than decreasing it. So if you know how to wear a face mask, it's a good thing to do, but if you don't, you're actually increasing the risk.
