How you think about stress can literally change your biology and lifespan—people with high stress who believed stress was harmful had a 43% increased risk of death, while those with high stress who didn't fear it lived longest. Kelly McGonigal, Stanford psychologist, reveals why reframing anxiety as excitement, volunteering, moving your body, and adopting animals are scientifically proven antidotes to depression, loneliness, and burnout. Your mindset about stress changes your physiology more than stress itself; believing stress is harmful increases mortality risk by 43% compared to people with identical stress who don't fear it.
