 I know you've been through the ringer over the past year, but I hear you very strenuously trying to not answer a question here. So let me rephrase it. Let me rephrase it. You're advising the Biden administration. And certainly the Biden administration, I know they're thinking about these questions because they've got to make announcements. They've got to communicate to the people, the CDC, etc. What are you advising them on what they ought to be aiming for regarding how we're going to know when COVID is under control?
