Yeah, Sarah, great question. I mean, look, I think we have been talking for quite some time, that we are focused on growing in areas -- first of all, higher acuity areas in our ASCs and surgical facilities. It is the highest contribution dollar per minute. And so it makes logical, since we're focused there. We also know it's what matters most to the health system, to payers, to CMS, the amount of savings we can drive is incredible for those procedures, often 10,000 plus a case. And that's why, yes, absolutely, you should see that mix continue to change. Now that doesn't take away the fact -- we love our GI business. We love our Ophthalmology business. They're great businesses. But when you think about our ASCs, think about de novos for example, almost all of them are ortho or cardio based. So like we are very, very focused on moving where we can add the most value, and that certainly provides protection against lower acuity stuff that maybe does change spaces. And look, we don't talk about that, but on the lower end of things, things leave our facilities, and that's okay because it's the right answer overall. I would like to point out, too, this is the recent CMS announcement, they added shoulders and ankles, in particular, total shoulders. We were really pleased during COVID, that we had some facilities that were accepted and able to do total shoulders. We had fantastic clinical results. We save patients a lot of money. Initially, they weren't included coming off the inpatient-only list. We were certainly pleased to see that, and we see those kind of opportunities to continue to push higher acuity patients safely into our space with a better experience, better outcomes and really just ultimately the best answer for the healthcare system, as a tremendous opportunity. One little set, I'd throw out to going back to the site transition, it's still 3:1, the number of joint -- total joints that are in the HOPD versus the ASC environment. So we're in the early innings of a lot of this stuff. You will see us continue to change that mix to higher acuity over time just because that's where [indiscernible].
