I, I think probably the, the biggest medical challenge and, and not based on animals being prone to illness or whatever, but just the volume of the collection. When I was at St. Louis, we had two, we had a pair of elderly gorillas, a handful of other great apes. And when I got to Lincoln Park, there were in the low twenties of gorillas and couple of groups of orangutans, a group of chimps. And so the, the number of great apes with their profile and, and the complexity of what we were able to offer medically was, was a big change. And, and I sort of, I sort of always felt like if there was a niche, I was mostly a primate veterinarian because those are the things that I remember taking up a lot of my time. And then we also had a rather successful breeding program with all the great apes and with the youngsters, ones that may need to be hand raised or need particular attention. You know, my subspecialty kind of became a grade eight pediatrician. So I, I’ve been around for, I’ve been around between Lincoln Park and, and here at Brookfield for something like twenty four, twenty five gorilla births, which is not an experience that pretty much anybody’s gonna get anymore.
