As the new science evolves, we have to spend some time keeping up with that new science, making sure we are abreast of new developments, whether we're talking about, for example, the introduction of new technologies or new biological pesticides. Nanotechnology, as you've probably heard in other discussions, is one of the technologies that are starting to make inroads. We have no doubt it's a technology that will be used in the pest control product field—not yet, but probably down the road—so we have to keep an eye on that.
We're very active in some of the 21st-century toxicology discussions with other countries, looking at non-animal testing and whether we can expand our use of non-animal testing in a bigger way, yet still provide the safety we need.
