Well, I think you're a great person to ask that Brandon because you’re so called the deep dive, so let's talk about LTL. I don't think we have John Smith here to here today. First of all, there are other carriers that do better than FedEx with the exclusion of perhaps a little smaller carriers and ones sort of I'm not familiar with, I believe the better way to put that is there's one LTL carrier that does better than we do. And that's Old Dominion, and we're great admirers of Old Dominion. But Old Dominion operates a network that has I believe somewhere in the 200 and some odd stations, versus our 360. They don't deliver every day to every part of the United States. And they've been very brilliant in finding a niche that's for lack of a better term near TL. It's in that zone between LTL and TL and their average weight per shipment in much more dense network is about 350-400 pounds higher. So their margins are outstanding, and they have terrific and obviously, we benchmark them carefully as our other competitors, which gets to you your point, do we ever think about doing things differently? And the answer to that question is we think about doing things differently constantly. Secondly, in the Express business, there is a belief, including you, Brandon, that somehow our Express operation in the United States is not profitable. Our Express operation in United States is very profitable. And we have some of the best industrial engineers and operations research people in the country. So there has been this constant mantra for 10 years that we ought to put Express and Ground together. Well, my goodness, we’ve gained market share in Ground for 19 out of 20 years. And Brie and Raj just told you we think it's going to continue and our competitive advantage is going to improve. So we're very convinced that the way that we are operating is the preferred way. And yes, we look at it at it every day. The third thing that gets people fired up. And I guess, Scott Group just mentioned it about CapEx is we are profligate in terms of CapEx. The reality is about $0.60 out of every dollar we're spending on CapEx are to modernize the Express hubs, to put in this new technology, we can't get people in Indianapolis and Memphis to work it. They're not out there plus it improves the productivity. So the failure to do it would be very dire. And as Alan has said, and we've said over and over again, every time we bring on a 767 and to a much lesser degree, the 777 because we're not buying many other of them. It's accretive to earnings, the reliability goes up. So could we stop buying 767, and 777s? Yes, why don't we stop buying them, because we put a chart on the earnings -- the IR website today that showed the synergy between the three major OpCos. So 80% of our customers buy all three of the services. So, if you took FedEx and tried to subject it, let's say to I think it was BCG that came up to that diagram, you have dogs and cash flows and one thing or another. If you did not improve the Express company, unless your costs get out of control, you couldn't win in the Ground sector and vice versa. So, we are very convinced and we put up a chart that specifically addressed your comments about this, FedEx will unquestionably be the low cost producer in the domestic Express business because of the fleet modernization and that includes any new entrance into the business. Yes, we have higher pilot costs and AMT costs perhaps, than the third-party providers. We think that's a good thing. But our total productivity and our cost per tonne mile are down 2% over the past 10 years, in this year's dollars. I'm not talking about inflated dollars, I'm talking about 2019 dollars are 2% less than 2009 dollars. So the fleet modernization, yes, we could stop it and yes, we could stop that CapEx, but the competitive positioning against our major competitors. And the last thing I'm going to say is, we basically compete in an ecosphere that's got five entities in it. There's UPS, there's DHL, there's a US Postal Service, and now increasingly, there is Amazon. That's who we wake up every day, trying to think about how we compete against and give the best services to our sales force. So, it reminds me of my days in the service where you run all these fake manoeuvres one thing another, it's a lot different when you got competition on the other side. So we try to beat these folks, UPS, and in particular has a very strong retail presence and both UPS and DHL have significant forwarding presences. So we’ve decided that we would basically cover those portfolio gaps with more focused capabilities, and that's why we operate differently. We carry retail freight on our purple tails and interline it, we don't have a huge forwarding operation. And we have a retail network that is smaller than UPS store franchise network, but utilizes partners as Brie talked to you about Walgreens, and dollar -- more recently Dollar General and some others. So the reason I'm going on about this, I'm not quite sure how this mantra got started, that we're hard hitted, or we're not willing to look, we'll look at anything. But what we can’t do is to change the reality of the math. We can't make the competition go away, I wish they would, just leave the field, they're very good operators. And the third thing that we have to deal with is the macroeconomic environment. And by the way, there's no company and no person that has been more vocal in our opposition to the trade policies that we are pursuing. Now, to be fair, I think it's not just the U.S., I think China is also pursuing bad trade policy. So you're taking a system over the last seven years that’s drawn more people out of poverty than in the entire previous history of the world, and essentially putting it all at risk. So these numbers on these macroeconomic production indicators, we didn't make those up. That's what's going on. So I apologize for the length of the response. But it's to this continuing drumbeat that somehow we're not willing to look at something and you take selective things like your LTL operation in as good as, all the others, it's not as good as one and it's not as good as the other ones in terms of margins for the reasons that I gave you. So it's important to look at this thing with those contexts in mind. Next question.
