Sure. And may be a surprise, it might not even be about COVID, I think what we learned is about the Artegraft acquisition and the use of debt and going large. And so I think that's been some of the biggest stuff that we've gotten JJ, Dave, and I have sort of digested for the year is that we need to go a little bit bigger with the acquisitions and I think we're a little bit more comfortable now using some other forms of capital. I think in the past, we've had a very conservative balance sheet. So, maybe that's one of my big lessons of the first nine months. If you're asking specifically about COVID, I would say the world from -- the company's breaking down into two segments right now. It's sales reps and the managers, and then everything else. And I would say, on a positive note, it feels to me like in Burlington here now, I hope there's not going to be some kind of COVID outbreak here. But it feels to me like the game is back on in terms of making medical devices, assuring their quality, having high levels of production, inventory, things like that. And so like all of us in this call, would probably finding some workarounds where we can kind of go do that thing, but we can feel safe about doing that thing. And I feel like in the five buildings in Burlington and I would extend this to the other factories at LeMaitre Vascular, we're getting about -- we're doing our stuff, we're wearing these watches, no one's bumping into each other. And so far knock on wood, we haven’t had any spread inside of the buildings at LeMaitre Vascular, I think there's about eight production buildings around the world that LeMaitre Vascular, and we haven't had any spread. So, I think the big thing I've learned is in first -- the first month, I was really scared of even going into the building. And I think now we're not. Many of us are coming back to buildings, we figured out how to get around. But then as I answered, Drew on the salesforce, there is something very different about the sales reps, they need to go out and get into other people's buildings. And I know that in our building in Burlington, our five buildings, there's a sign on the door that says don't come in, unless you're one of these 37 people that work here. And that's sort of where the hospitals are going with this. Unless you're very specifically asked into their hospital, they don't want to see you. So, I would say we're the broad -- 75% of our employees, the games on, we're doing stuff, it's getting back to work around normal, if you will. But with the reps, it's a lot harder and more difficult. And I think I've answered that question in two different ways. So, hopefully, you got something out of my lessons.
