What defines a short sleeper? what defines a short sleeper? they are able to bank longer sleep hours from the weekend as savings for their short sleep during the week. they are highly productive throughout the day. they are in excellent health. they can function well on 6 hours of sleep or less?

I believe the answer is: they can function well on 6 hours or less of sleep
On average, an adult need around 7-8 hours of sleep in order for their brain to function on optimal Level. Short sleepers on the other hand, could function T

The energy level that short sleepers achieve became the main thing that differentiate short sleepers with sleep deprived (A lot of people in large cities actually receive less than 6 hours slee but it's because they have too much work)

Lol that is s funny : )
