That's huge, but still, the study shows only about a third of the people eligible who should be getting screened are actually doing so. That doesn't sound great. Yeah, I mean, one in three is not great. It's better than, as you can see from the graphic back in 2019, it was one in five. We have a ways to go. I should point out that even though colonoscopy is the gold standard, stool tests can also be pretty good at picking up colon cancer at an early stage. What do you tell people who are hesitant to go out there and get this screening? They just don't want to do it. It can save your life. Almost every colon cancer starts off as a benign polyp that, over the years, turns into cancer. So if you have a polyp that's destined to become cancer and I go in and do a colonoscopy and remove it while it's still benign, instead of getting colon cancer, you don't. That's a home run over the center-field wall. To me, it should overrule any hesitation that you have. That's pretty compelling. Jon, thank you so much.
