This interview podcast features Andrew Huberman, a neurobiology and ophthalmology professor, interviewing Dr. Ellen Langer, a Harvard psychology professor specializing in the mind-body connection. The discussion centers on Dr. Langer's research, challenging conventional wisdom about health, aging, and mindfulness. Key studies discussed include one where elderly participants' biological aging markers reversed after living in an environment mimicking their younger selves, and another showing that chambermaids who perceived their work as exercise experienced health improvements. Dr. Langer emphasizes that mindfulness isn't just meditation but a way of being, actively noticing and embracing uncertainty, leading to improved well-being and potentially longer lifespans. Listeners gain practical insights into shifting mindsets to improve health outcomes, challenging limiting beliefs about aging and capabilities.
