This is such a wonderful endeavor featuring two authentic and caring people. It is clear that Zac wanted to use his fame to introduce important information and concepts to the audience he could reach, with the intention of contributing to the betterment of the world. It's really Darin's show, and his passion to improve the well being of humankind is obvious. The two of them worked to create a powerful message that is enjoyable to witness and learn from. A great experience.
