How is it that a breathalyzer can measure the alcohol content in someone's blood, hours after they had their last drink, based on their breath alone? And could we use this same technology to detect disease by analyzing a person's breath, without having to use more invasive diagnostic tools like biopsies, blood draws, and radiation? Julian Burschka details the complicated process. [Directed by Cabong Studios, narrated by Addison Anderson, music by Matheus Wittmann].
