Let me Sleep!

Its been pretty much shown that sleep cycles are heavily influnced by genetic makeup . While adults can override this with a fair amount of reliability, we shouldn't expect everyone to be at a certain place at a certain time, especially when we speak of children in school?

Think evolutionarily. Apes have no genetic reason to get up at any specific time. They don't need watches in the jungle.

"These results show that the gene is a central component of the mammalian circadian clock," the researchers from the Universities of California, Vermont, Utah and the Howard Hughes Medical Institute wrote in the science journal Nature.
