Yes. Again, as we said in -- all along, operating leverage is really the key component to the financial thesis. But, Q1 is typically low for us, if you were to go back in prior years. And the way I think about it -- let's start with R&D. I mean, if you look at our R&D spend this quarter, it was about $160 million. If you were to annualize that, as an example, it'd be about $640 million, which is on the low end of 7%. And now, we said, all along this year, in our guidance I think we provided, we said we'd be more at that 8% level. So, that's going to be incremental spend, if you think about the rest of the year, call it $50 million, $60 million. Same thing on SG&A. If you take that first quarter and annualize it, you get to about 34% as a percent of revenue. If you look at 2019, we were kind of at 38%. If you look at 2021, we're sort of at 37%. So, I would continue to expect to see some operating leverage there. But it won't be 3 points worth. So, again, you'll see some more spend on the SG&A front. The other thing I'd remind you of is if you look at Q2, again, if you go back to prior years, that's really where we amp up the DTC spend, some of the back to school spend on the contact lenses. So, it's not unusual to see Q2 SG&A go up, call it $60 million or $70 million from where we were in Q1. So, that's sort of how I think about the expense flow. But yes, I mean, the whole thesis is around getting operating leverage, we expect to do that to get to our goals. But if you just look at Q2, and it is unusually low.
