For a long time I can not understand - why not think up normal alarms on mobile phones? "Normal" in my understanding - this is so that "blindly" it was impossible to turn it off. As an option - it is necessary to dial an arbitrary set of characters on the phone, such as a code that turns off the alarm clock ... It’s necessary that a person at least opens his eyes ... And then, usually, turn off the alarm without opening your eyes, and then you don’t even remember that ...
