Facebook Overshare: 7 Things You Might Not Realize You're Telling The World

We share heaps of personal information on Facebook: birthdays, relationship statuses, geographical location and much, much more. In fact, with News Feed streams and Timeline-integrated apps, the line has blurred between participating in social media and completely oversharing the details of our lives.

One study from the Social Cognitive and Affective Neuroscience Lab at Harvard found that "our brains respond to self-disclosure the same way they respond to pleasure triggers like food, money or sex," per Today's analysis of the study. In other words, most of us like sharing online, and many of us may even find the act of sharing too much enjoyable.

But do Facebook users realize the amount of information they post? The dawn of the new timeline apps, which automatically post in-app activities to your Facebook profile, has created annoyances for some who never wished to spill certain details (however mundane they may be).
