We brought people in when I when I was at Dolby and had um had them watching Free Solo, you know, the Alex Hold movie where they're climbing LCAP stressful.
""Dr. Poppyrum mentioned "Free Solo" as an example during her explanation of how physiological responses like carbon dioxide levels can indicate human states. She described an experiment at Dolby where people watching the film showed real-time CO2 differentials, correlating with stressful moments in Alex Honnold's climb."
