Are you afraid of heights? Have you ever wondered why some people love mountain climbing in extreme conditions? Caspar speaks to 29 year old Josh Worley about The Vertical Year: his mission to spend 12 months climbing mountains around the world while raising $100,000 for mental health and environmental charities. Josh explains how climbing helps him confront fear and anxiety and break the monotony of everyday life. He hopes he can share these benefits with others by using his climbing to raise money for Reach Out and The Climate Council. You can read Josh's regular column at Zen and the Art of Climbing, or follow his exploits (and donate) at the Vertical Year website, on Instagram or on Facebook. This episode was produced by Nina Roxburgh and features music by Big Gigantic.
