And we’ve now documented a lot of these things. There’s still a lot of unknowns out there. There are a lot of emerging disease processes, mainly in the viruses, the bird influenza that has decimated the avian population all throughout Asia and it’s periodically touched us here. The one that also passes to humans. We didn’t know anything about this 20 years ago and don’t think it existed, but it probably did. Some of the, like the AIDS virus that came in, we now think it probably originated in Africa. It’s been around there for quite a long time. It’s carried by the ape population and monkey population transferred over to people when they kill and eat the gorillas, chimpanzees and some of the monkey species.
