Optimize Your Sleep For Better Health and More Free Time

Correlation =/= causation. I still haven't seen research that leads me to think that sleeping too long directly effects your health negatively as this article states. It is more likely that unhealthy people sleep longer due to overall health issues, not the other way round.
