Sure, Ann. And so, I think turnover, particularly in nursing, across the U.S. pre-pandemic tended to average in the low 30% range. I think most of our hospitals tended to do a little bit better than that, but obviously nursing turnover is and has been a significant, I think, challenge for the hospital industry for many years. During the pandemic, I think those percentages often doubled and in some cases, maybe even tripled. Again, not just for UHS and not just for acute or behavioral, but I think for hospitals across the country, I think it was particularly challenging for sub-acute providers like behavioral hospitals or nursing homes or home health agencies or any long-term care businesses who were losing clinicians to these incredibly sort of high priced opportunities to make these really premium amounts in acute care, COVID settings during the pandemic. I think what we said all along was that as COVID volumes diminished and reduced to sort of the levels that we saw in Q1 of this year, that many nurses would sort of return to their original or if you will, their sort of home base occupations or work sites. And I think we've seen that. I think we've seen a sort of a faster and quicker benefit to that on the acute -- on the -- excuse me -- on the behavioral side, where we've been able to fill more of our permanent vacancies. And as a consequence, we've been able to admit more patients. And again, the -- that 10% same-store revenue growth that we saw in the first quarter, I think is a -- very concrete reflection of our progress that we're making. I think on the acute side, we're making progress. We've, obviously, reduced our premium pay by almost half from where it was a year ago. I think a number of our peers have quoted, we have tended to talk about the wage issues in acute care by quoting our premium pay numbers. And that includes both things like overtime and shift differential that we pay to our own employees as well as contract labor. But when you just isolate the contract labor numbers as a percentage of overall salaries and wages, I think we're in that 5% to 6% range, which I think is right where our peers are maybe even a little bit lower than that. So, we've clearly made progress on the acute care side as well. And I think that -- while it's -- the acute care recovery has been a little bit slower, I think it positions the acute care business well for the rest of the year as acuity returns, as surgical volumes improve, the fact that we've been able to reduce premium pay so much from a year ago bodes well for what we'll be able to accomplish in the upcoming quarters as well.
