Early school

California is going to start school later because students are not getting enough sleep. This is based on the assumption that you cannot dictate that students go to bed earlier. If that is the case what is to prevent them from staying up later and still being tired? My experience with university students is that those who major in science, engineering and business are early to bed and early to rise people but those who major in the arts and fine arts are late risers. If that is the case then most politicians are lawyers and late nighters and they are making the laws. This is based on anecdotal evidence and subject to the foibles of such evidence. In other words it could just be nonsense.
