+1 I'm retired at an early age [54] and never set an alarm unless absolutely necessary. I wake about 30 minutes before the sun comes up and lay around dozing until I feel like getting up. I feel a hell of a lot better than if an alarm goes off and leaves me shaking like a dog trying to pass a peach pit.
