Have school start later for high school students

School should start much later than 8:00am. How are students expected to do hours of homework that is assigned and participate in sports? The result of that is going to bed too late and waking up too early. That affects the students ability to preform at their best. The early hours cause the students to sleep in class and fall behind in their education. Not only does it effect school, but it also effects the bond with your family. There isn't enough time to socialize and communicate with them.
