I went to a military boarding school. Plenty of exercise and fresh air. In bed and lights out by 10, with roaming patrols to ensure no noise was made. And still I tossed and turned until the early hours of the morning and was exhausted all day. Every fourth week on Sunday there would be no enforced wakeup time. Without exception the entire house would sleep in till early afternoon at least.
