Yes, that's a great question. Thank you for that. When I think of sort of optometry and big picture longer-term trends, I think of 3 things. I think first of employment. It seems that ever more, there's a desire to work in employee situations versus nonemployee situations. I think about flexibility. This generation, this post-pandemic period, that's flexibility in terms of days, but also modes of practice like our remote initiative. And I also think on a longer-term basis, sort of more medical aspects of practice are also going to be ever more appealing to optometrists. We have had a mantra for the past 15 years of we are creating environments for optometrists who want to spend their entire career. When I say environment, it's because we have a variety of different environments, everything from leasing to employee to just -- if there's a mode of practice, we like to have it available for optometrists in our various different brands out there. So the last trend I talked about was, longer term, more medically. As I said, we're doing millions of eye exams each year. We have thousands of optometrists practicing alongside our stores and in the National Vision network. And these optometrists are trained to not just find prescriptions, but to find all manner of ocular diseases and all manner of health care-oriented diseases. And that is a big part of what they do. Our optometrists are oftentimes to be first person to tell someone they have diabetes or hypertension, something along those lines. For many of our patients, it's the only interaction with the medical professional that they're going to have that year. So it's very important. We regard that as a big responsibility sort of offering the network of optometrists the primary health care. Some people have said to us, we are sort of an entry point for health care for a lot of our patients. Toku is an early-stage startup. Let's be clear on that. But the promise of patients being able to come to us and through a simple quick photograph of the back of their eye being able to assess all manner of health care-related things, diabetes, hypertension, cardiovascular disease, we think that, that can be an added value to the overall health care system. Again, this is longer range in nature. This is not about sort of how we're going to deliver this year's guidance, but we think that the network of optometrists who are practicing alongside our stores are playing an important role in health care in America and that technologies like AI, like Toku is advancing, can play an even greater role in health outcomes for patients. And we think that, that could be valuable to the overall health care of America at some point in time. And so we're signing a few teams to learn ever more about that and see what added value we can provide.
