Mimics - patient describes feeling tired or fatigued (not necessarily sleepy. Prevalence of short sleep duration (<7 hours) for adults aged > 18 years by county (us 2014) May include naturally short-sleepers skew the numbers. Boost their delta naturally with nothing wrong with them. Also with areas with smaller populations percents can be skewed.
