I too struggled for years during adolescence with early school start times and being generally super tired for the first 1 or 2 classes of each day. As an adult I also realize the pragmatic nature of school start times supporting our fairly typical 9-to-5 work culture.

However, I think it's important that we try to learn from this emerging data. If a body of empirical evidence starts strongly suggesting that starting school 1-2 hours later will improve information retention and learning, and if we collectively wish to maximize the success and potential of our youth then we must begin to change in order to support these goals.

I hope that by the time my future child reaches school age we will have begun to embrace a more data-driven approach to learning along with the necessary support structures to support such a change. Perhaps labor laws could be constructed to allow for more morning flexibility for parents that can demonstrate they are the legal guardian of a child whose age is between some range. I'll hope for the best.
