Yes, David. It’s a really pertinent question. And I feel very confident. And we've watched it. Before this recall was announced, through to June 2021, we saw great adoption for 18 months of all the digital solutions from doctors getting involved in telehealth to the adoption of identification, engagement, enrollment and diagnostic systems on a digital basis. In countries where, like in Germany, where it would obviously be interesting was less than 10% of the total diagnoses in 2019. It went to huge double digits throughout 2020 10% of the total diagnosis in 2019, it went to huge double digits throughout 2020, and it stayed quite high despite the reopening with COVID-cleaning particles of sleep labs throughout Germany. And so, I think as you look an aggregate, David, that adoption that happened in the last two years will be a huge impact, permanent adoption of digital health screening tools. And as Jim said, as we open up new channels, we're going to roll that digital end-to-end solution through multiple new funnels to get patients into the funnel through the early partnership with Prim [ph] through our CVS partnership. And they're the two public ones in the US, but we're doing, as Jim said, stuff in the other 140 countries that are more a partnership basis partnership basis with the UK government, with the NHS. Some great information from our UK team I was looking at over the last week, incredible work in our Northern Europe team. Our Western European team, the partnership with the French government. I talked about the ALASKA study that's just the peer reviewed, published evidence that's out there. We're doing stuff on the ground that we're not talking about publicly, but it has incredible adoption of digital health technologies in conjunction with the French Social Security system, supporting that through high reimbursement of cloud connected CPaaP versus non-cloud connected CPaaP. Because they see the results, they see high adherence, they see better outcomes, they see lower costs, not only death rate, lower death rate of those we'll see proper but lower hospitalization, so it saves lives and saves money. So, David, it's a permanent adoption. I think it will improve our efficiency as an industry, as we get into 2022, 2023 here and beyond.
