Our ability to process information and perform tasks peaks
between 11:00 and 12:00, so this would be the best time to
apply our brain to the most challenging daily tasks.
Teenagers are different. They peak later. There is a 2-hour delay
in cognitive ability to process information. Traditionally, the most
demanding subjects (like math and sciences) are delivered first
thing in the morning, when the kids are still asleep.
At 4 a.m., our cognitive ability is at its lowest and can be
compared to a legally drunk state.
