Trigger warning: This week's episode is an intense account of survival, which deals with heavy themes, including attempted suicide. Listener discretion is advised. Scoff and Wonk tell the amazing survival story of Mauro Prosperi, a competitor in the famously difficult Marathon Des Sables in Morocco. Prosperi was caught in not one, but two sandstorms and was left wandering though the Sarahara Desert in 115 degree heat with only some keen instincts and a small survival pack to help him while he awaited rescue (1994).
