melatonin levels

studying for my anatomy midterm, i just learned that the rise in melatonin levels is what causes people to sleep, and during different stages in life the timing of the release of melatonin changes, which is why teenagers sleep later (the melatonin levels rise later in the night).

well, i'm no longer a teenager and i can't stay up late anymore either... dang melatonin...

i need to stay awake to study!
