MIT researcher Nathan Eagle is helping mobile phones get to know you better than you know yourself.

How much does your phone know about your life? Perhaps enough to predict your behavior and even match you up with a mate, says Nathan Eagle, a graduate student at the MIT Media Lab. As part of the Reality Mining project, Eagle has collected approximately 40 years of continuous data on human behavior by capturing communication, proximity, location and activity information from 100 cell phone-wielding subjects at his school. Hidden in that data are insights about complex social systems that could affect our relationships with our mobile phones and each other.+
