Yes, so, thanks, Brian, for the question. So, as you know, and what I reiterated in our prepared remarks, we've been marching with our two-point strategy for some time. And the second strategy is to drive operational excellence, and we have maintained, and just reiterated, that we do believe we can continue to deliver 3% efficiency or productivity gains going forward. And that 3% comes from a variety of programs across Quest Diagnostics, and one of which is what we did in Clifton. And I actually also reiterated a couple other programs on the prepared remarks, are working with our suppliers with new integrated platforms, what we're done around immunoassay, what we're doing around our analysis is -- are two good examples of more work we can get the benefits from, and there's others. So, there's a lot more efficiencies in productivity we can continue to get. And as I said before, this isn't cost-cutting, this is improvement. And so, every time we make an improvement in our operation we expect our quality improves, and our service performance improves, and it has. So, we continue to make progress. You see it in our numbers this year, and you'll continue to see it in our '22 numbers as well. And that's always been used to offset headwinds, and we do have headwinds, we've had headwinds from wage bill increases in the past, albeit maybe it could be a little bit higher going forward, given what we see in the labor market. And then second is, we have seen headwinds from price consequences as well, which we've been able to offset, and we'll have some of those in '22 as we've outlined before. And then, also any additional inflationary pressures, we will be able to offset most of that, if not all of that, to be able to hit the outlook, and we just reiterated our confidence, our ability to do that. So, hopefully that's helpful.
