Exactly, that's right.
I can't really answer that. We can't predict what's going to happen in the future. The hormone techniques I'm talking about are evolving. We started out with reproduction. Then we included stress hormones. Now we're evolving into things like thyroid function, which was part of the orca study. We're also looking for non-evasive indicators of positive welfare, not just negative welfare. It's a continually evolving field of research.
