The histograms for restedness and sleep disorders would be easier to read if you put the key in the legend rather than in the caption so it's easier to tell which color means what.
Certainly my naive assumption is that age extremes are tied to sleep extremes; anecdotally the young and the old occupy both ends of the spectrum, so the people who sleep the most AND those who sleep the least will fall in one of these categories, while people in the middle of the age brackets will sleep a moderate amount. Children and the elderly are more likely to either sleep the most OR sleep the least. A strict linear correlation may not be the best route of analysis
Tue question "How long were you awake before you started your first scheduled task...?" is a bit unclear. How long in what units - minutes, hours?
thanks! adding the unit!

Looking forward to seeing the full debrief of your survey :)
There is correlation in age and variance of hours slept. E.g. if you sleep more than 9 or less than 6 hours, very likely you are young
