Harvard psychologist Ellen Langer discusses her remarkable mind-body research, showing how our mental perspective can directly affect our physical health. From studies where patients healed faster by simply believing they would, to experiments making older adults think younger and actually improving their biomarkers, her findings blur the line between mind and body. Langer and host Stephen Levitt explore how mindfulness – actively noticing new things – can combat stress, slow aging, and boost well-being. This episode will make you rethink “placebo effects” and inspire you to harness your mindset as a powerful health intervention.
