I, I think the, the big difference I, from when I started, the year I graduated from vet school, there was one textbook on zoo animal medicine and it was in German. And today there are volumes and volumes of literature on very particular topics in various animals. So today, some, an aspiring zoo veterinarian needs to, needs to be exposed to a, a great deal of the, the literature and the publications that are out there on the nuances of zoo and wildlife medicine. For me, in my time you had to extrapolate, we had domestic animals, human medicine and, and you were perhaps a little bit more winging it in terms of applying what you could from the available resources. Now you’ve been exposed to many things throughout your zoo career, not only zoo medicine.
