Maybe we've gotten a bit soft in the millennia since we moved indoors, but our survival skills are still pretty good. Our primitive brains keep us moving in search of food and mates and other necessities.
Trouble is, human ingenuity has resolved those quests, up to a point. We have abundant food, some of it good for us, and many ways to find potential mates.
Psychiatrist Peter Whybrow says we need to re-tune our brains for the world we live in now. His book is The Well-Tuned Brain: Neuroscience and the Life Well Lived.
Dr. Whybrow visited in 2015; we hear the interview again.
