Question-and-Answer SessionPaul MatteisStifel, Nicolaus & Company, Incorporated, Research Division All right. Sweet. Thank you. Okay. So I am like super, super excited for this tau readout coming up later this year. But I think one of the things that's hard to really answer in research about tau is the whole correlation causation question, which was a question with amyloid for a long time. Obviously, the correlation piece was like somewhat disproven. But as it relates to tau, can you just talk about like ta ...
