Every night, in rooms that belong to no one and everyone, travelers surrender their vigilance to the assumption of safety. Flight attendants — who have spent careers sleeping in unfamiliar cities — have quietly developed a counter to that assumption: a ninety-second ritual they call the hotel room autopsy, a six-step inspection that transforms passive arrival into active awareness. It is a small philosophy made practical, a reminder that in transient spaces, the only reliable guardian of your security is your own attention.
