This rut actually begins much earlier in some areas of the United States. Many high school students face early school start times and late nights of homework and studying. Add in sports, music lessons, extra curricular activities, or any combination thereof, and you get a recipe for sleep deprivation. Do that for 4 years of high school, and then 4-8 years of undergraduate/post-graduate/doctoral schooling, and you end up with some seriously sleepy people who have a hard time maintaining a healthy sleep schedule.
