 where your local wastewater plants test the water for COVID virus that people are shedding, shedding through their bowels, you know, into the wastewater. So that's the only data we have on COVID threat right now, while it's still a hugely dangerous and unknown disease we don't know enough about. I want us to be careful here, because a lot of people do tune in, and I want to be really careful not to push theories that we have no evidence or no facts behind.
