A Theory of Everyone with behavioral researcher Dr. Michael Muthukrishna

It's not just what we eat but how we eat it that counts. Eating the same meal in a different order can dramatically change how we feel! Glucose Goddess is the viral Instagram account of Jessie Inchauspé, who's inspired millions of people to change how they eat. With simple and easy dietary hacks, Jessie teaches people how to prevent glucose spikes -- large influxes of sugar into our bodies that make us tired, stress our organs, and cause us to age. Since adopting her eating habits, my energy has never been better. I was thrilled to talk with Jessie about creating Glucose Goddess and her personal story behind showing people a better way to eat.This...is A Bit of Optimism.

Anxiety disorders affect Gen Z at astronomically higher rates than previous generations. There's plenty to be anxious about in the modern world. But the reason behind Gen Z's mental health crisis might be simpler than you'd think.According to social psychologist and NYU professor Jonathan Haidt, the answer lies in growing up with a combination of smartphones and social media. In his new book The Anxious Generation, he argues that Gen Z's anxiety is a symptom of being the first generation to go through puberty on Instagram and TikTok, with iPhones available to access them constantly.Thankfully, Jonathan believes the problem is solvable. He shares some advice he has for concerned parents and tells me how we can fix the mental health crisis affecting our kids in just a few years time.This...is A Bit of Optimism.To learn more about Jonathan's work, check out:anxiousgeneration.comjonathanhaidt.comAnd for parents, visit:letgrow.orgSee omnystudio.com/listener for privacy information.

Most of us would count ourselves lucky to live to age 80. And yet, there are places on Earth where people regularly live to 100, suffer virtually no chronic disease, and live life with a sense of purpose.  These "Blue Zones" are the focus of Dan Buettner's work. He's a National Geographic explorer, an author, and a documentarian. He spent years traveling and studying the Blue Zones to understand why these 5 places on Earth produce some of the happiest, and longest-lived, people in the world.  Dan and I discuss why happiness is the key to longevity, creating Blue Zones in our own lives, and how a longer life can begin with simply rearranging your kitchen.This...is A Bit of Optimism.

If great leaders are those willing to suffer for their beliefs, Leopoldo Lopez is certainly a great leader. After he led the massive 2014 Venezuelan protests that swept the nation, the regime of Nicolás Maduro sentenced Leopoldo to over a decade of political imprisonment. He suffered four years of solitary confinement and psychological torture before he escaped.  Leopoldo tells me about his time in prison and how he cultivated the mental strength to endure. The story of how he smuggled himself into exile is a truly remarkable one. Most of us will never experience military prison, but what Leopoldo discovered about surviving enormous stress is something each of us can learn from.  This…is A Bit of Optimism.   To find out more about Leopoldo and his work, check out: worldlibertycongress.orgSee omnystudio.com/listener for privacy information.

The thrills of pleasure-seeking don't last long before we need even more. And when the excitement isn't enough, what is? Scott Harrison's life as an elite nightclub promoter was an unending cycle of drinking, drugs, models, and fast cars. After ten years, his vices caught up with him, and a health scare forced him to reflect on his life. Scott felt decadent, wasteful, and morally bankrupt. He decided to completely reverse course. Scott spent the next 2 years in West Africa on board a nonprofit hospital ship, where he saw a level of human suffering that led him to his true calling. Today, solving the global water crisis is Scott's life's work, and he's built one of the most trusted nonprofits in the world to do just that. His organization charity: water has raised over $750 million, helping more than 17.4 million people access clean drinking water. Scott shares with me the painful road that led to his transformation and why living a life of service can be a path toward redemption.
