In respect of the second set of questions that Mr Woodhouse asked, he rightly noted that a range of factors over the course of the year of COVID have resulted in a range of measurements in relation to communicable diseases being significantly reduced, and he noted influenza as being one of them that's of sentinel measure in our society. Of course, a big part of that were the heightened public health measures, but I think a very big part of it was the fact that people have had a much, much greater awareness of the need to stay at home when they're unwell to prevent spreading illnesses. Now, the main driver of that has been COVID, but I have absolutely no doubt whatsoever that it's had significant flow-on benefits.
