Should schools start later in the day

YES! The current schedule messes with teens sleep patterns. Teens get tired at 11pm. So if 1st period starts at 7am thats not enough sleep. Yet younger kids, (more awake in mornings) have later start times.

Definitely. Most teenagers in high school are stressing over classes, and have no time between work and sleep / sleep and school. It's tough, and it causes loads of stress.
