 Okay, and I've recently experienced this in my family because some of my younger family members, they're having kids. And so, you know, the whole birth experience, especially when it's the first kid, it's very fraught. They want to know, you know, what should they do? You know, should they, you know, accede to a C-section or should they have a home birth? You know, there's all kinds of different considerations. But one of the options is to bank some cord blood.
