 So it's a very, very important type of thing to, one, check out. And as I tell a lot of people, because it's interesting, people come in, they have a palpable thyroid, you can see it, and their doctor's been telling them that it's fine. Then you can see it. Right. And it's not fine. It's not functioning properly if you can see it and palpate it. Right. You know, that's a dead giveaway. It's just that it's not being evaluated properly.
