You know that you have biological alarm clock in your body. If you want to wake up at 4 o'clock for example, you can set you body alarm clock, and it will wake you up at 4 o'clock. But capitalism era forces you to go work on time, people think that they need artificial alarm clock as backup. And the problem arises when you combine both. It will become your habit to lean on the backup to wake you up, so you will miss alarm coming from your body, and it will become your habit to ignore your artificial alarm clock because your body not ready yet to wake up.

This is dilemma in this digital era. You can not depend on your main resource reliability anylonger, because computer is very unrealible. So you need backup. But combining both probably result in disaster.
