 was actually mandated to go to address learning loss. That's Lance Izumi. His new book is called The Great Classroom Collapse. Teachers, students, and parents expose the collapse of learning in America's schools. Lance, thanks very much. By the way, I've got to tell you something. When I go on vacation, I make sure I'm wearing my G-Defy shoes. In fact, I'm wearing them right now because G-Defy shoes make it a whole lot easier. I stand up about 12 hours a day, and I feel better at the end of the day because of that. But your feet can hurt, not with G-Defy's.
