 Now in terms of we also understand that Mr. Floyd had previously been diagnosed with COVID-19, right? Correct. And he may not be symptomatic, have been symptomatic on March 25th, but it's fair to say that a lot is unknown about the effects of COVID-19 on a person's long term. I mean not as much as it would appear to be the case, I mean because obviously it's a viral illness. We have a huge amount of information about the long-term's effects of viral illnesses. And those can affect the elasticity of the lungs, right? Not the elasticity. It would be if it's having any effect it would be within the sensory receptors within the trachea bronchiol 3. So it really wouldn't have anything to do with the elasticity. Okay. Now but we also learned quite a bit about the toxicology as well. Excuse me. On the COVID-19 you testified that treatment of people with COVID-19 includes leaving them in the prone position, right? Correct. And so those people who would be treated for COVID-19 in the prone position, based on your calculations you would have a 24% decrease in the EELV. Right. I mean this is people with COVID where they're during the time that they have COVID. Right. That's what you'd expect, that same decrease in the EELV. No, it's going to be very different. In somebody who has, say, pneumonia, what's going to happen in the prone position will be very variable from one person to another as a result of the pneumonia. It's different than normal lungs. Okay. So in essence every person is different. Oh, for certain. And now you calculated his respiratory rate to be 22, right? Right. And you said that that was within the normal respiratory rate. Yep. And you would not describe him as hyperventilating. And the word hyperventilation is open to an awful lot of misinterpretation. That is most certainly not hyperventilation. And hyperventilation assists in the removal of carbon dioxide from the body, right? It's confusing. It's not that simple. In its simplest terms. In the simplest terms, yes, it does. It gets rid of carbon dioxide. But it can be frequently misleading. Okay. Now in terms of the toxicology of Mr. Floyd, we did learn that there were some controlled substances in his system, right? Yes. We know that there was, for example, nicotine, right? Yes. Mr. Floyd was a smoker. Correct. And smoking changes the lung function, agreed? In some people. Now, we also learned more, and I'm not suggesting that all people who smoke have lung problems, right? Less than 10% to 90% don't have any. Just a microponics.
