This article got a score of 3.5 because it is still credible and there was no bias or incorrect statements within the article. My main issue with the article was the lack of takeaway gained from it. There was not much research or explanation about why more sleep makes you live longer. They presented data from a survey that helped their case, but most of the second half of the article articulated how there is not enough data to show why. This article is credible, but can be skipped.
