 And it wasn't until a few years later when we moved back to the United States, had three healthy children. I was teaching in a rural high school setting in the area that was filled with a lot of poverty and a lot of apathy. And I had some kids coming through my classroom, lots of kids actually, who were suffering from issues of attendance, suffering from issues of academics, suffering from issues of behavior. And I kept asking myself, what is it? What is going on? Why so many children suffering from this?
