Bedtime

You know when you were a child and your mom could tell you were sleepy and she made you go to bed?  I always refused, but got forced and I was tired so it wasn't long before I was at the mercy of my own eyelids.  As an adult, however, I often find myself trying to stay awake longer.  Like I'm defying all those who used to tell me to go to bed.  I find myself sleep deprived and tired though.  Why do I do this?  I feel like I need to accomplish more and that sleep is wasteful.  I know I'm not alone, the CDC says that 30% of Americans habitually get less than 6 hours of sleep.  Wonder why that is.  Oh well, I'm sure they are no negative consequences, we know better than mom anyhow right?
