The science of sleep

Jesus, your genes really do control absolutely everything. Kind of a duh statement, but you never really think about it.

"The people with the DQB1*0602 gene variant were sleepier and more fatigued while both fully rested and sleep deprived. Their sleep was more fragmented."

The gene they're talking about is usually present in people with narcolepsy and those of us who are sleepy all the damn time, or need more than 6 hours of sleep to function. I think I probably need less, but I don't get very rested sleep. I'm up all night long, tossing and turning.
