So a lot of that is people going to Google and searching. We want to provide high quality health information. But also, we see there's a lot of personal health information that's being generated. And it's hard to keep track of. It's all in paper form. And so we do think that we'd ultimately like to be able to offer people a way to keep their personal health information online. So you could see test results, X-rays, an overall catalog of different conditions and things that have happened over time. And have those all in one centralized place, so it's portable, you as the user have control over it. You could bring it with you to different doctors and really ultimately empower the user to get better health care." When might you be announcing a formal type product that would do that? "We don't usually predict launch dates, but I do think that there'll be activity in the very near future." How big of a business could it be for Google? "I think it's a very big business.
