I do, right, and I'm not alone in that, a recent paper was put out by 21 very well internationally-respected virologists and evolutionary biologists who said the same thing as I'm saying. And I rely on people like that, who have great experience in this. That's what they do every single day -- who, again, are open minded -- and are saying it's conceivable that you may have had a lab leak. So you've got to keep an open mind to all possibilities, but they feel that the more likely explanation is a natural evolution from an animal host to a human.
