Yeah. Thanks for the question, Robyn. Some of the – let's say, the number that I'm about to give you might surprise you a little. So first of all, if you take R&D, let's split it up into R and let's split it up into D. So firstly, R, we have three research sites. One of those sites is focused on cystic fibrosis there. It is focused on other targets as well but it is primarily our cystic fibrosis site and they've done excellent work, as you know, out in San Diego. There are two others sites that are not focused on CF. So already, we're spending well beyond 50% of our research investment beyond CF and on disease areas that, again, we've touched down on this call, that are similar to CF but we have a research strategy that goes beyond CF already and we've been doing that now for a couple of years and we hope to start seeing some productive results in taking molecules into the clinics of diseases that you may be familiar with, and they should start to see that maybe later this year and certainly, into early part of next year coming out of research. So, we're already – if you wanted me to put a percentage on it because it's fungible but it's probably around 60% that's beyond CF, given how we carve up our research activities. For development, it is a little bit of a different story. Oh, and by the way on the research, we're committed to maintaining that kind of approach. I don't think that's going to change in the near term, given we continue to invest in CF. And I'd also say in research, we start to supplement it with external relationships such as CRISPR and Moderna and we have an investment there as well. When we look at development, development is principally an investment in cystic fibrosis right now. As you may imagine, we have a full pipeline ranging from Phase 2s all the way through to Phase 3s. And so, the principal investment in development is actually towards CF and it goes well beyond just clinical trials as well. There is a heavy support in terms of formulation, manufacturing, medical affairs and regulatory. And so, I would say probably 80% of our development spend is towards cystic fibrosis. And again, I don't see that the investment in cystic fibrosis tailing off significantly for another three, four, maybe five years. You have to understand as we get approval for medicines in 12 and older, we immediately are thinking about how we get approval for medicines in 6 through 11, we're thinking about 2 through 5, we're thinking about how we gather longer term data and build our registry data to support the long-term outcome of our medicines of treating this disease long term. So, we need to maintain that support for the medicines we're creating to treat CF. I do see the investment starting to increase beyond CF but that would be a function of those creating opportunity. And Jeff just talked you through the pain opportunity. We have to see how that plays out, but you will start to see new ideas coming to the clinic and we'll start investing in those. But it'll be earlier stage so it won't be a significant spend in the next two or three years. It would grow if they progress down the pipeline.
