Why does the alarm clock snooze button give you nine extra minutes, not ten?
8:00:00 am<p>alarm clock begins beeping<p>8:00:15<p>I actually begin waking up<p>8:00:45<p>I manage to get up and silence the dumb machine<p>8:10:00<p>alarm wakes me up again after initial snooze, ten minutes after I intended to be awake<p>If the snooze went in ten minute increments, and a person was fond of snoozing, after a handful of snoozes the time delay between alarm sounding and snoozing would add up and throw off the mental calculation.<p>"I've hit the snooze five times, it must be 8:50, oh shit it's actually 8:55, FML," versus, "I've hit the snooze five times, it must be 8:50, oh hey it's actually only 8:47."
