Driving while phoning, scrolling social media at a desk, studying with music on: multitasking has become the default mode of modern life, and this DW documentary asks what it costs. Neuroscientists explain why the brain cannot actually run several complex tasks at once, showing how the attempt raises stress hormones and wears down grey matter over time. Occupational psychologists and business management researchers bring in the workplace angle, citing a large study across companies in 20 sectors that links multitasking demands to a 25 percent drop in staff retention. Sociologists add the cultural piece, tracing how remote work and constant connectivity turned juggling tasks into an expected skill rather than a choice. The film moves between lab demonstrations, interviews with researchers, and footage of people working under exactly these conditions, building toward the question of whether anyone can opt out of the pressure to do everything at once. It ends less with a fix than with a clear diagnosis of the damage.
