Yes. No, overall -- maybe first kind of at a high level, Jack, that when you think about kind of the headwinds as we go into 2023, and Adam kind of alluded to and you did as well in your opening comments, but COVID testing, we'll know more, obviously, when we give our guidance in February. But the assumption is that it's going to be down pretty materially next year and following the trend that we've seen. But again, we'll have a better assessment when we give our guidance. But to your point, we did around 60% margin on COVID testing this year. And again, we talked about the going forward 24% tax right now. A big variable, again, as Adam commented on is PAMA. We've looked at around an $80 million to $100 million, if you will, range of an impact. But again, by the time that we give our guidance, we should know whether or not PAMA will be in the numbers for next year or not, we'll see. And then just the additional headwinds from the current inflationary environment and the labor constraints. Having said that, we really see a lot more positives than the headwinds that we're seeing. The demand levels, especially the momentum that we've seen in the Diagnostics business, not only have we seen volume levels pick up sequentially each quarter but even through the months of the quarter. So the expectation is that, that will continue into the fourth quarter and continue into 2023. And also, when you think about the correlation, while we're giving up high-margin COVID testing normally when -- if the expectation is that, that will be down to low levels, bodes better for the Base Business within Diagnostics as well. Similarly, Adam commented on the level of demand in Drug Development isn't the issue per se. It's more the kits issue that we said really hasn't come back to 2019 levels. And this is really the only aspect of even Drug Development, and it's really just the kits that are being returned. And so the expectation is the demand is there, the backlog is strong, the conversion that kits returned should come back to more normalized levels, and then hopefully, with the labor capacity issue abates a bit as well. And then you add to that another strong year of focus on cost measures, LaunchPad initiatives, another strong year of free cash flow generation, that will add to a good pipeline for acquisitions, let alone returning our capital. So when you stir it all together, we're actually pretty optimistic for '23 where we sit today. From a top line perspective, from our ability to drive margin improvement, realizing that we'll have headwinds from PAMA potentially as well as the annualization of Ascension will be a little bit of a margin headwind as well. But those combined with capital allocation, we feel actually pretty optimistic as we go into 2023.
