In this episode, Michael explores the evolutionary backdrop that molded human beings, a setting characterized by scarce food, limited information, and few possessions. He contrasts that with the modern era, marked by abundance and comfort, and the ensuing repercussions on our physical and mental well-being. Michael introduces the concept of the “scarcity loop,” a three-part behavior cycle which helps explain modern challenges such as overeating, addiction, gambling, and materialism, and offers practical strategies to break free from its cycle. The episode culminates in a thought-provoking exploration of happiness, drawing on Michael's experiences with monks and underscoring the value of boredom, exploration, and discomfort as transformative elements that elevate awareness, presence, and the will to live.

His extensive research into human behavior has helped him identify key components of habit formation and develop the “Four Laws of Behavioral Change.” In this episode, James provides insights into how both good and bad habits are formed, including the influence of genetics, environment, social circles, and more. He points to changes one can make to cultivate more perseverance and discipline and describes the profound impact habits can have when tying them into one’s self-identity.

In this episode, Arthur returns to the podcast to discuss his new book, Build the Life You Want. He delves into the nuanced concept of happiness, differentiating between momentary feelings and overall wellbeing. He explains the importance of understanding one’s personality pattern with respect to positive and negative emotions in order to better self-manage emotions. He delves into the three key elements of happiness, offering practical strategies for enhancing those specific domains through methods such as metacognition, transcendent experiences, discipline, minimizing self-focus while directing attention outward, and more. Through personal examples, Arthur demonstrates that one can actively track well-being levels and take intentional steps to cultivate happiness and enhance overall well-being.

In terms of individual lives saved, you could argue that there is no other person on the front lines doing more than Tom. Additionally, we explore the manner in which the Nuba people die, which is in striking contrast to the ubiquity of chronic disease and self-harm in the West, despite the extreme poverty and unimaginable suffering experienced by the Nuba people. Lastly, we discuss the lessons to be gleaned from the Nuba people, who, despite their suffering, live so harmoniously, happily, and resiliently. We discuss: ---Background, medical training, and early days of missionary work in Africa [5:15]; ---Tom arrives at Mother of Mercy Hospital in the Nuba Mountains of Sudan, civil war breaks out, and his staff evacuates [12:30]; ---Learning surgery on the job and earning the trust of the community [37:00]; ---The amazing people of Nuba, and why Nuba feels like home to Tom [47:45]; ---NY Times article about Tom’s work, and Tom’s new venture on the board of the Aurora Prize Foundation, raising awareness and funds for other missionaries [59:45]; ---Tom’s mind-blowing ability to deal with chaos while seeing hundreds of patients per day [1:12:00]; ---The most afraid Tom has ever been, and how he copes with the emotional trauma of his daily experiences [1:19:45]; ---The basic tools, technologies, and medicines that Tom is lacking that could save many lives [1:30:00]; ---The logistical challenge of helping Tom’s hospital, and what Tom really needs [1:35:15]; ---Diseases in the adult population [1:38:30]; ---Living without possessions, finding meaning, and being a missionary [1:55:45]; ---Happiness, sense of purpose, and suicide: contrasting the US with Nuba [2:07:15]; ---Other than donations, is there a way people can help Tom and other similar causes?

He examines the available data on these drugs, assessing their comparative effectiveness and their potential in the context of lifestyle interventions. Additionally, he offers insights into whether SGLT2 inhibitors hold promise as geroprotective agents beyond their effects on glycemic control. Next, Peter analyzes the relationship between statin usage and the risk of developing insulin resistance and type 2 diabetes, investigating possible causal pathways and providing insights into strategies for risk reduction. He offers insights on monitoring adverse statin effects and evaluating the need for adjustments, ultimately weighing the trade-off between the risk to overall metabolic health against the benefits of reducing apoB levels through statin use.
