We began our conversation with internationally celebrated photographer Howard Schatz by focusing on the nature of creativity and and the challenges of creating "phenomenal" images when so many images are unoriginal, easy to access and abundant -- though the abundance, Schatz feels, makes it easier to determine what is great. He spoke about his interest in the human form and the mystery of art as well as his recent book, PAIRS, anchored in the idea of the diptych. He spoke, too, of the necessity of knowing what is going on in one's chosen field and why it is singularly important not to previsualize, as well as the backgrounds on his computer screen, photographing flowers and nudes and how practicing medicine helped him to be more human and a better photographer. A rich and deep conversation.

He also had a number of significant observations on the American health care system, including ways AI might be used productively. He talked about how and why he became an expert on aging and ways that marketing and ads have changed to include older people, as well as how overall stereotypes tied to aging have morphed. We concluded discussing the X Prize Foundation (Ken is a trustee), and its commitment to finding ways to match health span to life span as well as the importance of humor (Your host even told a joke) and youthful versus useful.
