 Let me ask you this, too, because a lot of scientists that have been on this program tell me that a virus is not alive. And I just don't understand that. I don't get that. What do they mean by that? It's basically like, for instance, with Corona here, we've got an RNA virus that needs a host to complete its process. So it's going to use your cells to replicate itself. In this case, Corona loves to be in your lungs.
