Unpopular Proverb

On Habits

Early to bed, early to rise, makes a man healthy, but wealthy people are notorious night owls and wise people didn't necessarily get that way due to their sleeping habits. I think we have an endogeniety problem on our hands--do wise people engage in healthy sleep patterns? Or is wisdom a result of healthy sleep patterns? I submit that further research is required.
