Sure. They were looking at prescribed medication and they didn't see a decrease. We have found a decrease in prescribed medication, and so have some of the studies coming out of Purdue and so forth. We also looked at other types of substances, like alcohol, marijuana and things like that. The VAC study didn't, but again it was a preliminary first study. It was the same for us.
I keep saying here is an exploratory; here's a preliminary. We are in our fifth year now. We have a much broader, stronger study, but we're growing. With that evidence base, if we had this meeting five years from now, we would be saying something different. Underlying all of that is that we as a society do not recognize what animals contribute to our lives.
