Dr. Darby Saxbe reveals the surprising science of the "parental brain" and how fatherhood physically reshapes a man's mind, why dads lose grey matter, what really happens to testosterone, and why the "dad bod" might be nature's design. Dr. Darby Saxbe is a professor of psychology and a leading researcher on the neuroscience of parenthood. She is the founder and director of the NEST Lab at the University of Southern California, and is also the author of ‘Dad Brain: The New Science of Fatherhood and How it Shapes Men's Lives’.

Financial Crash Expert: He Predicted The 2008 Crash, Now He Says Capitalism Failed, It’s Too Late!

Is the West collapsing, or is the planet? Political commentator Konstantin Kisin and rebel economist Steve Keen go head-to-head on the biggest questions facing the West: immigration, the debt crisis, climate change, Trump, China and the future of AI. Konstantin Kisin is a satirist, social commentator and author, best known as the co-host of the Triggernometry podcast and the author of ‘An Immigrant’s Love Letter to the West’. Born in the Soviet Union and now based in Britain, he has become one of the most prominent voices on free speech, culture and the rise of populism. Steve Keen is an economist, author and one of the most vocal critics of mainstream economic thinking. A former Professor of Economics, he is the author of several books including ‘Debunking Economics’ and ‘The New Economics: A Manifesto’, and is currently writing his upcoming book ‘How Economists Will Destroy Capitalism’. He is known for his work on private debt, financial crises and the failures of conventional economic models, and for correctly warning of the 2008 financial crash. They debate: ◼ Why almost everything governments tell you about debt and borrowing could be wrong ◼ Whether a socialist government could actually be good for the economy ◼ Why AI could quietly strip away human free will ◼ Why Konstantin believes mass immigration is pushing the West toward civil unrest ◼ Why Steve thinks climate change, not politics, is the real threat that dwarfs everything else CHAPTERS * 00:00:00 Intro * 00:02:05 We're on the Road to Civil Unrest * 00:08:04 Where This Leads: Unrest and Violence * 00:11:11 I Grew Up in the Soviet Union * 00:12:12 Steve Keen: Capitalism Is About to Fail * 00:20:49 "We're Not Spending Enough" * 00:23:58 Should Britain Drill in the North Sea? * 00:28:39 "You Can't Defend Yourself Against This" * 00:32:48 The World Government Admission * 00:36:55 "Brace for Impact" - Climate Change Is Here * 00:40:03 "It's Too Late" - What Breakdown Looks Like * 00:45:11 The Trap Trump Walked Into * 00:48:49 The Famine He Says Is Coming * 00:50:53 How Does Trump Get Out of This? * 00:53:35 Does America Need a Socialist President? * 00:55:37 Why China Works and the Soviet Union Didn't * 01:01:10 "Would You Prefer the Chinese System?" — "Yes" * 01:05:09 Will Andy Burnham Change Britain's Trajectory? * 01:11:00 Wokeism: A Hierarchy of Oppression * 01:13:30 AI, Mass Unemployment and The Hunger Games * 01:17:21 Best Case a Pet, Worst Case a Cow * 01:20:54 Can You Program Love Into an AI? * 01:26:07 Nobody Can Stop It So How Do You Live?
