Look, for people to be -- it almost sounds terrible to say it. But for people to be exposed to dust and pollen, they need to be out and about and not wear a mask. And then, we can help with allergic rhinitis product, as well as more COPD although that has been less impacted. And of course, if people wear masks all the time, their likelihood of contracting the flu and the finical [ph] is much lower. That is the negative side of it. It's good for people, but it's not so good for the treatment. Now, on the vaccine, you already mentioned that. As people get vaccinated and hopefully key countries or key markets get north of that magical threshold whatever it is 75%, 85%, where everybody moves about, then, yes, we benefit both from the vaccine and from the higher incidence of allergic -- allergies and cold and cough and flu. And the effect can only be positive in that scenario. Plus, if those booster shots materialize to any extent, I think that will be continuing boost to that business, not surprisingly. Now, if everybody is back to indoors, wearing masks, then of course, we have a very different scenario, but that will also impact the beauty business, the beverage business. So, by now we've established a pattern. But if we remain positive and it certainly looks like the US government is determined to get those vaccination rates up. And I think, Europe, behind the US initially is catching up and is also pushing for high vaccination. I believe those two markets seem like it will balance out very good for Aptar. China is a mixed bag. Vaccination rates are low. So they control the pandemic through harsh lockdowns when something happens and basically, closing the country off for outbound tourists as well as inbound tourists and business travel, so -- with the effect that the -- it's more a Chinese domestic game and we are well advised to continue hurrying up to increase our footprint, to take advantage of the large domestic economy that China is. But clearly, the lack of travel and that will stay with us as long as Chinese vaccination rates don't go up, has a negative impact on our beauty business.
