Thanks very much, David. We absolutely recognise not just that long COVID is something that people are going to have to live with, and as you've seen, we've developed an app to try and help recovery for people, which we've launched this week. But also, we've got to focus, I think, on particular groups. Some of those are people who've had a prolonged time in hospital and critical care, so that's one group of people we've got to understand. People who, perhaps, are not being directly impacted by COVID, but have been indirectly in the sense that they were waiting for a different kind of operation, and that can lead to mental health issues. There are people, of course, who've avoided accessing services because they were concerned that they may catch COVID, or whatever, while they're in there. And also, there are socially isolated groups where lockdown has really increased the pressure that they have felt, and that lack of social connectivity. So, there is a lot, I think, that we need to recognise, and slightly different aspects. 

It's clear that every person who lives with a mental health issue has to be dealt with as an individual, and that it is a uniquely individual issue that needs to be understood. But I do think that we, as a community now, need to understand that we have gone through trauma, as a society, and that trauma-informed approach needs to inform our response to the pandemic. Certainly, the oversight board will have COVID as something that we keep an eye on and that we need to remain flexible with. 

The other issue that I think is probably worth noting is that there will be a particular issue, I think, with people on the front line. And it was interesting to speak to the Royal College of Physicians last week about what they see as being an issue in terms of the longer term, that, actually, people on the front line have not got time to think at the moment, but when this is over, the kind of post-traumatic stress could really kick in and they're suggesting that that could take about three or four years to actually hit. So, we've got to put all of that provision in place to prepare for what could be quite a significant impact on the people who are on the front line.
