Loud Alarm Clocks
We all need alarm clocks, and I don't care what you say, I can't wake up without one. Sure, you can get int the rhythm of getting up at the same time if you do it 50 times in a row, but you know that there are some of those days, when you wake up, and you were in the deep sleep. Thankfully for the alarm clock, you were able to wake up because of it going off.
