A study conducted by professors at Columbia and the University of Pittsburgh reports that those who spend more time on Facebook are poorer, fatter, and lazier.
According to an article in The Wall Street Journal, one part of the study analyzed how much time people spent on Facebook, and found that the pro-stalkers had greater body mass indexes and lower credit scores. In another part, participants who spent time on Facebook took a cookie over a granola bar.
The study also showed that those who are glued to that magnificent shade of blue are much less determined: people who had spent just five minutes on Facebook were more likely to give up faster when asked to solve impossible anagrams than others who had been Facebook free.
Just based on personal experience, correlation is definitely leading me towards causation with this one.
What else would I do as I scroll through my news feed and judge most of my Facebook "friends" on their over-sharing, their statuses about their lives that are anything but humble brags, and photos that show the Freshman Fifteen the especially mean ones gained?
