I sleep 5-6 hours a night
I have had this same sleep pattern my whole life
When I was a boy, my parents made me and my brothers go to bed at 8pm
While my brothers slept, I stared out the window, dreaming of places to go and things to do
My students often *think* that they can live with less than 7-8 hours of sleep
(because they must to cover school, homework, work, and a social life)
The VAST majority of people NEED 7-8 hours of sleep a night
However, a recent study found a genetic marker for people like me
There is a very simple test to see if you have this genetic marker
When you do not have to wake up for any reason (holiday, weekend, etc), do you sleep in longer?
If you sleep longer on the weekend or when on vacation,
you are NOT getting enough sleep during your normal life

Sleep deprivation has some VERY significant costs (physical and mental)
If you are not getting enough sleep, alter your lifestyle
