Yes, as I mentioned to you earlier, to find that right balance, it depends on the area. For example, in the area of medicine—molecular biology, genetics, and so on—there's a tremendous potential for targeted research. There are other areas that are just as important that don't appear to have the potential for commercialization immediately, but if you're not investing in these areas now, what will happen 10 to 15 years from now?
If I can take a personal example, we've developed a sunscreen cream based on research done on photosynthesis. It has nothing to do with medicine. We've developed a sunscreen that has higher efficacy to protect against UV light than anything that's on the market today, simply because of evolution. Photosynthetic organisms have to deal with light all the time, and they've evolved a mechanism to do it. All we've done is exploit that. If you weren't doing research into the environment, you wouldn't have discovered it.
