 Well, and I want to be careful here because I don't think there's been any official findings. I know they're doing studies right now. How COVID-19, one of the effects of that was a change in hearing on one side. I do know that within my own practice, I did see it. How we're going to track that, that's going to be years from now. But I saw it in my clinic. And so just kind of waiting to hear on what the official word on that is. But I did see it.
