do they need sleep?

The government complains about teenagers not getting enough sleep. Several times the government has contemplated making school times start later and end later, so that students can get enough sleep to survive the day without falling asleep in every class. Every time, they drop it because they think it is the students fault for this. Yes, we have lots of time to sleep, assuming you slept right when you got home until 7:20 the next morning to get dressed for the bus ride to school, which comes at 7:30 and you get to school at 8:00. You are also expected by teachers to do lots of homework each day for each class, you also have to eat, shower, are encouraged to have some physical activity each day, and in the morning you are expected to have a nutritious breakfast which would take at least 35 minutes to make and eat, then 2-5 more to brush teeth, and whatever else you may need to do like brush your hair or put on make-up or whatever which would take another 10 minutes or so. So i think that you do not have enough time to do what is expected of you and get enough sleep (8 hours per night) to properly function each and every day.
