Varför är oftast snooze alltid 9 minuter?

För ett väldigt lång tag sen satt vi och funderade hur det kunde komma sig att snooze knappen alltid skjuter på alarmet 9 minuter. Varför inte längre eller kortare? Jag har för mig att vi totalt glömde att kolla upp varför det är så. Så jag vart helt enkelt tvungen att dra ytterligare en googling idag och se där, google kan allt! Här kommer svaret:

"A: By the time the snooze feature was added in the 1950’s, the innards of alarm clocks had long been standardized. This meant that the teeth on the snooze gear had to mesh with the existing gear configuration, leaving engineers with a single choice: They could set the snooze for either a little more than nine minutes, or a little more than 10 minutes. But because reports indicated that 10 minutes was too long, allowing people to fall back into a 'deep' sleep, clock makers decided on the nine-minute gear, believing people would wake up easier and happier after a shorter snooze. We’d tend to disagree with that logic, but, then, we must be in the lazy minority. Although today’s digital clocks can be programmed to have a snooze of any length, most stick with nine minutes because that’s what consumers expect."
