I think the prevalence of trying to prevent disease as opposed to treating it after it’s obviously present have been very important to us. And it’s been a continuum that’s been growing, we would much rather spend time on doing lab work on blood or on feces to find out if an animal might have a latent infection of heartworm or of trypanosome, or might have malaria, in the case of some of the penguins, some of these things are important instead of just waiting for them to get sick, show obvious signs and or die and diagnose it at the knee crop scene. So preventive medicine, the fact that we have so much more information, and the fact that we have more tools to work with. We have a lot more immunological tools that we can see what animals are allergic to see what they have been exposed to. And they may not be showing the disease, but they may have been exposed to it and, or they may be a carrier for it. So the fact that we have more scientific knowledge to work with has been a good thing. As far as treatment and what we’ve seen there, a lot of the newer evolving drugs, if you stop and think about it, we didn’t have the first antibody until World War II. And since that time now we’ve come through several generations of good antibiotics.
