 And recently we've been working with some schools with kids with autism or learning disability. And actually we have an educational director who's been using our technology frequencies in these classrooms. They couldn't even count to 60. They can't even go and memorize the alphabet. That's how they scored in math. After four months of using our frequencies in the classrooms, and they can't even sit still for nine seconds, right? Now they're sitting still for 15 minutes or longer in the class. How are they now teaching their kids? We couldn't even approach them before. They would scream. We spent years trying to give them talk. And in four months now they're leaving the classroom. Now after four months, they are scoring the top 1% in the nation.
