Yes, Landry. So we don't pay every order for kind of a Raven code of why might be coming in, but we're, of course, Barry, close to our clients all the way up into the C-suite, and that's exactly what we're hearing right now, is that a lot of the demand, is just purely they're vacancy rates that they have the attrition rate, but, they've had it around facility. So I think it's probably one of the biggest reasons, is not reason that we've seen some of the pretty big increases over the last five weeks to six weeks, so seeing sequential increases, and over the last five lease or six lease, we're nowhere close, to where the orders were in that December, January timeframe, they were extremely high, at that point. But, another thing to point out, is that, it's not any one client, it's not any one specialty, is not any one geography, we're seeing it across the board, new demand and total demand being enough. I'd also mention Allied, even with the COVID hospitalizations, that decline there, they have continued to see really strong demand there, they actually even today, they are at all-time highs, that we've never seen in the business, and one of the good things there is that, it's rare, that we would see every specialty within Allied, and that's what we're seeing today. I know, we've talked previously about therapy, of physical therapy, and occupational therapy having some headwinds, at the end of 2019, and if you look at the demand, that we're experiencing there right now if you look, last year that double digits and now, it's in the hundreds of workers that we have. So really hard numbers, and the good thing about that, is that we have really great recruiters there, and we have a great database, we're really good at staffing physical therapy, occupational therapy, so interested to see what they do here over the next couple of months, or on a great trajectory, if there was one specialty within outlined, that I would point out that is down year-over-year it's respiratory, and really the biggest reason for that against some really hard comps, from prior year. But, where we are today, it's still quite a bit higher than what we would have seen pre-pandemic.
