Vijay, glad you picked up on that, which is we believe this asymptomatic approval is an enormous win for us over the long haul. And let's face it with what the world has gone through here, even post vaccine, there is going to be probably some pretty strong ongoing needs by governments around the world, who want to monitor their health -- their populations, and just track on an ongoing basis, just to see relative incidence or any kind of recurrences. And frankly, it's the asymptomatic people who are the key there. And that's the on label indication; it's hard for us to probably fully underscore how strong we think the demand will be for that for years to come. Yes, and you still play out the timing of vaccines, by the way, let alone mutations and other things. We believe and we've been in close contact with most of the major governments around the world, all of the key labs, the health experts, we believe an ongoing screening program, where you're going to want to use the most sensitive tools out there, including, frankly, hospitals are going to want to continue to test patients coming in, what is the best way everybody is going to go in for a hip and knee, cardiac any other procedure, we think, at least for the next couple of years, is probably going to be tested. And again, with our global installed base now in excess of 2200 and continuing to grow on Panthers. We think this is going to be a big, big, enduring market for us, is it going to be exactly what it is today? Yes, likely not. But there's going to we believe, and we've made the bet that there's a longer tail. if you look, by the way, just one other data point, the contract we got from the US government last week, if you look at it, they're asking for us to be providing 13 million tests per quarter, by per month, really six quarters from now by the first quarter of 2022. So again, governments are increasingly planning to want to have major capacity well beyond even just this coming, cold and flu season.
