Fall asleep to one of the deepest, most soothing voices you've ever heard reading the most inconsequential material there is. Fall asleep to the ultimate authority for human engineering in space: NASA-STD-3000, "Man-Systems Integration Standards." This episode focuses on Section 5: Human Performance Capabilities. Relax as we process the rigid requirements for astronaut functionality, including the calculation of Minimum Character Height (16 arc minutes!), the required chromaticity boundaries for color-coded displays, and the acoustic criteria for auditory alarms. Sleep secure in the knowledge that every action, from a simple control movement to a complex procedure, has been measured, contained, and deemed acceptable for the 5th percentile female. This technical reading is designed to replace conventional bed time stories with structured boredom. An alternative to standard short bed time stories, this episode offers the focus of a sleep meditation podcast that can also soothe adult ADHD. Deeply Unimportant's adult bed time stories consist of pure, unchallenging data—sleep stories meant to be ignored.
