In 2017, Fresh Air marked 30 years as a nationally syndicated, daily radio program by doing what it does best: more in-depth interviews.
But when we looked back at this year's most popular Fresh Air interviews on NPR.org, one story ruled them all: Terry Gross' interview with sleep scientist Matthew Walker. You'll find that, and much more, in this list of the 10 most popular Fresh Air interviews of 2017:

9. Author Says Hitler Was 'Blitzed' On Cocaine And Opiates During The War Author Norman Ohler says that Adolf Hitler's drug abuse increased "significantly" from fall 1941 until the winter of 1944: "Hitler needed those highs to substitute [for] his natural charisma."
