The Diary Of A CEO with Steven Bartlett

What actually happens to your brain, and how fast or slow do you age when you become a parent? 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 (Neuroendocrinology of Social Ties) Lab at the University of Southern California, where her pioneering work studies how the transition to parenthood changes the brains, hormones and relationships of both mothers and fathers. Her research has reshaped how scientists understand fatherhood, men's mental health, and what it really takes to raise a child.

What if getting better sleep has less to do with sleeping longer, and more to do with your daily habits?

Dr. Kristen Holmes is a performance scientist whose work focuses on sleep, recovery, circadian rhythms and the everyday behaviours that influence how well our bodies and minds perform.

In this moment, Dr. Kristen Holmes opens up about her childhood and the catalyst to her passion for health and human potential. She reveals the overlooked habits that can quietly disrupt recovery and answers common questions about sleep disruption. Is one glass of wine really going to impact my sleep? What about caffeine? If I don't have time for 9 hours of sleep every night, can my sleep still be restorative?

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

Professor Brian Greene reveals the biggest questions science still can’t answer, whether we’re living in a simulation, why AI may deserve human rights, and what happens at the end of the universe! 

Professor Brian Greene is a theoretical physicist, mathematician, and Professor of Physics and Mathematics at Columbia University, where he also directs the Center for Theoretical Physics. He is a leading researcher in string theory, the co-founder of the World Science Festival, and the bestselling author of several books, including ‘Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe’. 

He explains:
◼ Why most physicists believe time travel into the future is already possible
◼ Why he believes humans don't actually have free will
◼ How string theory could reveal what everything in the universe is really made of
◼ Why the "Pale Blue Dot" changes how you see your own life and problems
◼ Why the search for meaning may matter more than finding the answer itself
