Yes. Thanks, Vijay. Thanks to everyone for joining the call. Maybe a couple of macro comments. One, I just think this represents another quarter of strong execution, consistent with what we shared overall. When you think of our kind of forward-looking view from our updated guidance, I think, a few key things, not that we highlighted and then I'll address your question maybe with where we see some pockets of strength. But one, we did increase to your point, 50 basis points of growth on our base business. That strength is pretty broad-based when you think of it. I'll come back to that. And that's despite the fact that you had the restrictions and impacts in China as well. So we more than absorbed that. We also absorbed the COVID-only testing revenue, which given the testing dynamics in the marketplace are not surprisingly down when you think of COVID only relative to our position in the market. That's a higher-margin offering, and we absorbed that as well. I think importantly, we continue to execute against our margin, and we committed to our – at least 100 basis points of margin improvement and then we incorporated FX. Yes, and to your point, when we're entering the year, I mean, one, Q1 is still under-indexed relative to our full year guide. Right? So that still holds together. We know there was about 100 basis points of headwind associated with the licensing revenue impact in our Life Sciences business that you saw in our results. We had estimated there is maybe about another 100 basis points of other dynamics, comp-related issues, mostly attributed to COVID. We also had some difficult comps in the quarter in certain areas like pharma systems, for example, grew 18%, Q1 last year, and we still delivered north of 10% growth in this quarter. So, I think that continues to be a source of strength for us. I think the flu season, there is probably a timing dynamic there. It peaked a bit earlier than we thought and was a higher spike. As we go through this call, Dave can certainly amplify that, but it's played out like it's played out in other areas with a quick season that's going to abate. So I think you have a timing dynamic there as well. So there is various items such as that. But largely speaking, I think, things are very consistent. We feel really good about the first quarter of the year, and it gave us confidence to increase our guidance.
