The other thing is if you have something that reduces the hospital stay, the mindset is that stay is just going to be replaced by another patient coming in, so you're not going to save money. It really is a system look at it. If you have enough products you utilize that reduce the stay, the stays would actually reduce. But there's such a backlog in our system, in terms of waiting, that if there's a product that saves three or four days in the hospital, and then you go to the hospital, they'll just say, no, because that is just going to be replaced by another patient.
It's that simplistic. It's very pragmatic at the interaction level.
