I just watched this 2003 TED Talk video lecture by Wade Davis, the pioneering ethnobotanist and anthropologist who has lived with an amazing array of indigenous cultures around the world. Of course, Davis is best known for his studies of ritual use of psychedelics and also the zombification practices among Vodoun acolytes in Haiti. I've found Davis's work to be personally inspirational, provocative, and mind-expanding. This TED Talk, titled "Cultures At The Far Edge of the World" is no exception. In it, he tells an amazing story about an wonderfully resourceful Inuit elder.
