This short documentary considers the role of technology in the lives of two people: Matthew, a San Francisco designer who has never owned a cellphone, and Tess, a teenager who couldn't imagine a day without hers. Filmmaker Ivan Cash has a great compassion for his subjects, as we've highlighted before , and this short is no exception. "I would recommend that everyone, regardless of their age, goes out in nature for extended periods not connected to anything," Matthew says. "That's a huge shift for people."
