Yes. So, kind of a question did you are, John. We one doesn't know for sure, of course. And this virus is as predicted, right? Second wave already in the fall and the winter as it gets colder with increased infections and etc. So we think two things. The principal impact to our RMS business although other aspects were impacted. But the principal impact was academic major academic medical centers across the world, particularly the U.S. and Europe closing abruptly really two or three weeks. And so we know that, number one, their -- sorry that, that happened in retrospect that, that wasn't a thoughtful response on their part. Of course, they didn't understand this virus very well. And now that they do and now that they see the impact of that we're quite confident that the academic medical centers have made arrangements, both and they're very structured, how they work? How they PPE? How they stagger shifts? How they utilize, foods, etc. That they'll be able to withstand this apparent and already increase in the incidence of infection. So we don't think that we're going to have a major dislocation again that they'll all take a deep breath. We don't know -- what I'm about to say, we don't know, but I would be very surprised. Again, given the education that everybody has about the importance of mass and social distancing, and being careful who you hang out without sort of -- hang around without sort of work and staying home and you're sick, all of these things. I would be surprised if small biotech companies and large pharma companies shut portions of their sites for any meaningful period of time, if at all. So, I don't know if we stated. I mean I thought right now, and of course, we're in the midst of the second wave, the second wave, and the first wave and a new second wave for sure, you still think we're going to exit the year pretty much at a historical run rate for research models, both products and services. So, China will be strong in services. We'll be strong in the U.S. and Europe, which would be by COVID will not be. And we think it's highly unlikely that there will be a major sort of, I mean, unless there's a major shutdown across these sites, which we can't imagine what the rationale would be given the learning curve that we all have and all these institutions have had. So highly unlikely, John.
