I am not a morning person! With that said, I believe that early start times should be eliminated at school and at work. A good start time for school and work is 9:30 or 10 AM.

Great question

I go by the old English poem:

Early to bed Early to rise Makes a man Healthy Wealthy and Wise.

Usually, the early bird gets the worm ! After a good night sleep, the human brain has best capacity in the early morning. The children, as well as the adults, can be trained to wake up early within a short duration & the "biological clock" will be adjusted to the desired mode as life goes on.

You know that Summertime has been set for saving purposes & we will surely utilize one to two precious morning hour(s) by "easy" adaptation.

In most of the public school education in Jordan, after the 1967 war and for several years we had to share our schools with refugees comming from the west bank of jordan after its occupation, whichinstantaneously doubled the number of students to educate In our country. Schools were used twice, for the first group of students from 6:50 to 11:30 AM then for a second group from 11:50 AM to 04:30 PM. Yet very few or even probably almost none of students suffered "depression"a word very rarely used in Jordan.
