Thanks, Anthony. So just to start on your first question, again, we don't have clairvoyance on this. I would expect the first quarter where we had this confluence of structural factors, including meaningful lockdowns, right? We feel like your society at large is better relative term, of course, at dealing with the pandemic. So we don't, we're not at this point anticipating widespread lockdowns. But we may see situational things geographically. But I think we're beyond that, and we kind of know what we have structurally. Big open question around college campuses. Many are intending to open, will they stay open? How will that attitudinal demographic differ than what we've seen through the main nucleus of collections. They are important factors, and we're, again, cautiously optimistic about that. But within limits, right? And I think that you underestimate this pandemic and the effect of this pandemic at your own peril. So we need to continue to be thoughtful about that. We do think that we, as an industry, collectively, have the ability to improve from the base that we've experienced so far, we are learning and our customers, and we are responding accordingly. So that gives us grounds for cautious optimism. In terms of the shortage question, it's obviously, quite important, the U.S. is now responsible for 90% of the world's sourced plasma supply. 85% to 90%. There is -- they collect their own plasma and they occasionally buy recovered plasma from Chad's, Blood Center customers. That was a much larger number, 3 or 4 years ago. It's dropped pretty meaningfully, and those collectors have their own challenges, meeting the demands for whole blood and red cells and platelets. So from our vantage point, getting these centers fully operational and back to their practice capacity is priority one. All of our customers are working on it. We're working with them. And I think that we will do everything within our power as an industry to avoid those stock outs, the best of the challenge that we face into right now.
