So, I mean, it's not, it's not just a one-time thing, and it also like it costs money. So that's the other thing where I think doing the study is important because right now, uh, a lot of insurance agencies will cover it, you know, in Canada, you do need to sort of uh advocate to the health systems to cover it. So having this data that shows its effectiveness, I think is actually, it's really useful to have.
