This is pretty much the core of privacy that we're losing - the ability to reinvent ones self. At age 18 I left just about everything I knew behind, and I'm not sure it'd be possible to do so now. We have things like bankruptcies that go off of your record in 7 years - I'll bet if given the choice banks would love to see them forever. Full information is not always a good thing - it almost always ignores people's ability to be flexible.
