Snoozing

While this has nothing to do with martial arts, I thought others might find interesting. I've always wondered why, when I hit the "snooze" button on my alarm clock, there's an interval of 9 minutes before it sounds again. Today I finally looked it up. Here's what I found, if you're interested:

By setting the snooze time to 9 minutes, modern digital alarm clocks only need to watch the last digit of the time. So, if you hit snooze at 6:45, the alarm goes off again when the last digit hits 4 - at 7:54. They couldn't make the snooze period 10 minutes, or the alarm would go off right away - or the clock would take more circuitry.

That question's been bothering me for a while. Now I can rest easy ;o)
