But the second thing is they almost never get heart attacks. The, the, the same sort of myocardial infarct, the thing that, you know, is characterized as a heart attack in humans. They have other cardiovascular disease that are not unheard of, but less typical, more unusual in humans. And so we had an interesting, an interesting issue, and I gave a presentation in 93, 94, somewhere in there where we said this, this seems to be one of the key areas health wise in gorillas, if not the chief one. We need to, we need to find out more about this. And particularly at, at the time I talked about that nobody had diagnosed these cardiovascular problems before the animals died, you know, which makes treatment pretty difficult. So we said, you know, we need to, you know, it’s certainly a challenge, but it, it would be good to do more diagnostics, particularly echocardiograms to ultrasounds to see what’s going on with the heart, to try and figure out how this thing progresses. And that led to discussions.
