So, the big push in their literature and MIT and what they've been admitting 30 years ago. Was that they had on military facilities all over the U.S. animal human chimeras, but they didn't have rights because even if they put 1% cow or 1% pig, which splices well with humans, or 1% rat, just like we don't, you know, they test on rats, they test on pigs, because for whatever reason they're closer to us in any effects, but also, you know, we don't reject as bad things that are closer than us in the genetics. So they've had these chimeras, admittedly, 30 years ago, when I was first on air a few years, it was like it was. People were sending me, here's MIT Quarterly.
