Yes, I will start, and I will let Matt chime in the end if he needs. But I think, Stephen, it's a great question, it is a very important stat that we are very focused on here in the company, because it does inform how you think about bidding for new users, as you said, on LTV basis. And it all stands from as the most basic level it's around everything in the product, right? So, when we bring you in, and you signed up for your product, it's having a great experience, it's ease of payment, it's great customer service, there is a problem, right? So, all these things we have to nail the product experience first and foremost, right. And that person exited bad experience with a great experience. And to say that this is something that I really enjoyed and wanted to do again. Then I think it is important around the brand awareness, and how we are then -- our ability to remarket and reengage with those users. So, really goes across all the things that Viator is doing, product experience, customer experience, and then how we then keep engaged with that user. And I'd tell you the more we are doing ties into the CDP work we are working on, the more data we have around the individuals, the more customized we can be, the more customized we can be that means we are just going to offer unique and differentiated things on a personalized customized basis that others just can't do in the category. So, we are very excited about that.
