 So, we're using our system to help their children because a lot of them have mental health problems. And another program we did is called Frequency Methods. So, we're helping kids with ADHD and autism, learning disability. We actually use our coils for three years in classrooms already. And then we have a case study. We go to our site. We show how these kids who are the lowest in the class went from that to the highest in the nation in four months. Wow. It's crazy. Okay. And this is quantitative. This is their math scores. So we had the lowest math scores in the nation. These are kids with ADHD, autism, learning disability in the worst class. They did the math test four months later. They're scoring in the top 1% in the nation. It's crazy. How did it happen?
