This BBC video on work-life balance and burnout shows the positive effects of walking to reduce stress and burnout. A South Korean businessman affected by burnout and chronic stress runs 10,000 kilometres a year. This has helped him improve health and train his body. It also helps him think clearly. He started doing this after several startups led to chronic stress and walking seemed a natural way out. It started with a4 hour run from Busan to the ocean in South Korea which he told friends he could do. This turned into walking tens of kilometres every day. He developed his own style and now shows people in South Korea how this is done.
