Host Todd Conklin interviews fatigue expert Mark Rosekind, PhD about his path from sleep research to roles at NASA, the NTSB, and NHTSA, and how sleep science applies across transportation and safety-critical work.

Key takeaways: think of sleep like a bank account (sleep debt), "start in the black" before major schedule changes, the benefits of strategic naps, and systemic ways organizations can reduce fatigue to improve performance, health, and safety.
