NPR Ted Radio Hour combines multiple Ted speakers that talk about their topic and which all relate to each other. Topics range from psychology, nutrition, science, leadership, etc. In this podcast five Ted speakers talk about one (or multiple parts) of Maslow’s hierarchy of basic human needs: physiological needs, safety needs, belongings and love, esteem, and self-actualization. Topics include why we need sleep, what it takes to feel secure, what war teaches soldiers about love, what defines a person’s sense of self, and what makes a life worth living. This is one of the most popular episodes of NPR’s TED Radio hour.
