A professor of geography at UCLA, Jared Diamond looks back to humans' former lifestyle through his own fieldwork in traditional societies that still exist or were recently in existence, such as the highland peoples of New Guinea, Andaman Islanders, African Hadza and North American Inuit. Diamond highlights the many crucial lessons to be gleaned from 'primitive' societies, pointing to life decisions that may help us live longer, healthier lives, enjoy old age, and raise self-confident children.
