The first question was on novelty. Again, I have to emphasize flexibility, because you could have something that's registered that has very small use in a very minor area. You can't suddenly say, even though it may be a long time, and something is very widespread.... You don't have to look just at Canada. Look at the U.S. Look at Brazil. Look at other nations where this has been occurring for a long time. In my opinion, it's based on animal feeding and a whole analysis; time is one factor, but there is exposure, and all those other things. Not finding any documented, validated risk is a key thing.
One other point that I think needs to be made when we talk about this technology is that a lot of it is actually at the analytical stage. I'm not sure if you're aware, but right now, the way we're selecting our Holstein cattle is by their genomes. We look at their entire genomics, and we say that these are the genes related to milk production, and those are the ones related to health. We can now select the best calf or the best bull not by rearing it out and doing all those records but by looking at its genes. Canadian companies are leading in that as well. It's also very much a tool for progress rather than, necessarily, a product. I think that's important to talk about.
On your next question, I'm sorry, novelty...?
