Hello there!
Could some expert try to "simplify" (but not too much) the very cientific and detailed explanation given about the mutation of the DEC1 and DEC2 genes in regulating the overall time we need of sleep?

PS: remember, not that much simplified, as I'd like to know what exactly mutation of these genes do to make sleep times lesser than the usual in humans - why? would it be that mutation in these genes make our cells spend less energy so that we go to bed "less" tired or would it be that mutation in these genes changes somehow the sleep patterns (for example, more of deep sleep which is the recover sleep)?
