Been a classic short sleeper my entire life. I remember being 5 and my parents going to bed whereas I insisted on staying up because 'sleeping was a waste of time' I told them :-)

I am 45 now and still feel this way. I sleep 5-6 hours tops and after those rare nights when I get more than 6 hours of sleep I feel sluggish and beat all the day. I love having all these extra hours available to me and am accomplishing much more than those who do not have the benefit. I use the time to exercise, read and work. Neither of my children inherited the gene apparently...
