Let me speak generally to capital expenditures and where we are at this particular juncture, and then Bill can speak to the returns and how we analyze our capital spending from that standpoint. We are increasing our capital spending from 2020 level. We spent about $2.8 billion, $2.9 billion this past year. We're going to approximately $3.7 billion. We believe, as I mentioned in my comments, that a lot of this increase is going to some of our growth plan initiatives that we have. I think one thing that's very important to HCA Healthcare, and I hope you all appreciate and understand, is that we have a unique portfolio of markets that we serve. And when we look and score objectively the HCA markets that we serve compared to the national average with respect to certain economic indicators, roughly 2/3 of our portfolio of top markets outperforms, and in many instances, outperforms the national averages as far as forecast very significantly. So we still have growth opportunities embedded in our portfolio. That's the first thing I would tell you. Secondly, we are investing in our outpatient facility development. A reasonable point of reference is roughly every 1 of HCA's hospitals has 10 to 12 outpatient facilities attached to it. That's not exactly symmetrical from one institution, but when you look at the total outpatient facility network capabilities we have, it's roughly 2,200 to 2,500 outpatient facilities on top of 185 hospitals. So, it's roughly 10 to 12x the number of hospitals. We will continue to build on that because we believe that our patients deserve a convenient offering of facilities in our network. That doesn't require, fortunately, as much capital as the in-patient components of our spending. On the in-patient side, we have a handful of projects out there that we felt still made sense. Most of them are in these high-growth markets; Dallas, Texas; Austin, Texas; Nashville, Tennessee; Jacksonville, Florida, places like that, that are on par with respect to demographic changes that appear to be occurring across the company. We don't want to miss those opportunities. Fortunately, a lot of our investments are long-lived assets and we're in a situation where some of the historical capacity that we put into the market will serve us well in the future. And then as we look at what's already in the pipeline, the $3.3 billion that I referred to, those are going to supplement our capacity. And then by then, hopefully, we're starting to get better visibility into what's happening with demand, and then we can adjust accordingly. So, at this particular point in time, we're not giving any additional long-term guidance on CapEx, but we believe we're in the zone of what we need in the near term to be responsive to the marketplace, competitive, provides the patient safe environment that we want, and ultimately, achieve our overall objectives. So, Bill, you want to speak too?
