I guess the only thing that I would would would sort of draw out is this idea about in a way, lockdown is just a shorthand for a range of activities. And that's going to differ depending upon the jurisdiction. And that's true here, as we all are currently in Australia, different states are going to have different approaches. So it's kind of I think, if you mentioned the word lockdown to people, two years ago, sort of pre COVID, they would have been horrified about the idea in western democratic states, whereas so many countries have now moved to different forms of lockdown. So I think, thinking a little bit about that, you know, when when in China, the initial response was to focus on using these kinds of methods. I think there was, from many politicians, certainly the expression of the idea that this was extremely problematic, and it would never be accepted by Western democratic nations, and that we would never be using it as as a measure. But yet, here we are. And I think it's an interesting set of reasons that I guess we'll get into is thinking about, what is the relevant evidence here? Do we have evidence? And also think about the... the more ethical questions, you know, what has changed in the, in the mindset in relation to the acceptability or potential legitimacy of a lockdown?
