I agree with you when you say that the school should start much later I always ask myself that question, they are children and they need to sleep, rest their body
As a child it was difficult for me to wake up early, I think that affects us a lot, just like going to work many times it is very early and you leave so late that you do not have time to rest.
I used to be creative, read at night I think it's my best moment only now tiredness takes its toll
