Yes. Hey, Mark. I'll take both of those questions. On the first one, with respect to large problems to solve, I think first -- I think this probably goes without saying, but I think it's worth repeating, just given the resilience or continued resilience, I should say, of the strength of the restaurant delivery business. And even though that business has achieved a great deal, it's still single-digit percentage representation of the U.S restaurants industry in terms of total sales. So I think I don't want to just skip over some of the businesses that we do run today versus just talk exclusively about the invention of new businesses or solving new problems. So I think there's still a lot to solve in our core business, which I believe has many, many years of runway in it. And when we talk about some of these new categories, that's obviously almost starting just many years behind, given the fact that we launched a lot of these new businesses, about 2.5 years ago. So I want to start with that as context, but I think when you talk about a lot of local commerce, I mean, let's think about it. I mean the pandemic in many ways was a very alarming and aggressive wake up call for every business to be an omni-channel business. And I think it -- for a period of time forced physical retailers to exclusively invest in online because that was the only channel available to them. But I think that as we now kind of, especially as e-commerce goes back into a bit of the steady state curve of adoption, I think there's a lot of problems there to solve, I think that there's the world only tends to want to go faster, customer expectations tend to only go in one direction, when it comes to something like delivery, whether that's with food or other types of items beyond food, that is only going to happen at a greater and greater rate, and if you're a physical retail, or you need to think about how you’re going to participate in that. And so there's lots of logistical problems we have to solve in order to do that. And we're investing quite tremendously in building up certainly these partnerships, but also in a lot of infrastructure, so that we can create the tooling with products like DashMart, such that we can work concurrently with all of these retailers so that they can actually compete, I think at the highest scales with global ambitions. So, I think that's a big part of still making sure that last mile delivery can be true, not just for a handful of retailers, but for every retailer, small, medium, and large. Second and beyond this, there's a lot of tools that now local businesses need to invent. I think a lot of times people think, oh, e-commerce, that's just a website, or that's just a mobile app and you're done. Well, actually, everything needs to be rethought, right. For example, if you used to take care of customer support requests inside your store, whether it's a shopping request, or a dining request, well, you can't do that anymore, if the orders are happening through your digital channel. You're going to have to invent customer service in a different way. If you're used to being once very successful buying real estate at the right locations at the right prices and effectively using that as a way to market, well that's no longer good enough. And there's going to be many ways in which you're going to have to think about not only attracting customers, but building repeat relationships with all of the customers that you do have. And so, I think there's lots of problems to solve. But whether that's in logistics, whether that's in customer service, whether that's in, honestly, every part of what you do now needs to turn from physical to digital. That's what all businesses need to do. So there's a lot of work and the roadmap ahead is quite lengthy. Your second question was about Wolt. In short, Wolt is meeting our expectations which are really high to start with. I mean, in general, we tend to have very high expectations of ourselves and I think when you look at the Wolt performance, or the thesis, I should say, starting a couple of years ago before we close the partnership a year ago, it was really betting on a world class team that has achieved the highest retention and order frequency, in other words, build the best product in the world. And whether or not we can keep growing those geographies, which had long runways for growth as well as take some of their exceptional management, and run a global portfolio. And so those are kind of the two thesis involved in a couple of years ago. And on the first point of whether or not we can keep growing, I mean, I think you kind of see it in the growth rates. We're growing at multiples of what anyone else is growing internationally. And we're also improving our unit economics at the same time. And so, I think, from a business perspective, that's really meeting the bar. The second is more of a management perspective. And what you see there is that we'll actually, Mickey and the team actually runs all of DoorDash's markets outside of the U.S. And so I think we're seeing a very, very strong start on that front as well as that team now is taking up a bigger geography. And we now get to split the management bandwidth in the right way, so that we can give international, which is a huge investment area for us the right single threaded focus and do the same for our U.S business as well.
