From the article:

> Adolescents in the U.S. are chronically sleep-deprived, in part because most schools start too early.

The goal of changing the start time is to allow students to sleep more.

But changing the number on the clock doesn't mean students will sleep more. Allowing students to start at 8am instead of 7am will just mean they go to bed and hour later because teenagers are terrible about going to bed on time.

You're massively over-generalising there. Some will do that, sure. But this should make it better for some teenagers, without making it worse for others. That sounds like a good solution.

They aren’t changing the number on the clock like Daylight Saving Time did. They’re changing when you are required to arrive. They number on the clocks are staying fixed and that’s why it’s more likely to help.

They should just schedule one third of the classes to be online and from midnight to 2am.
