An interesting observation in Joel Brenner’s book, “America the Vulnerable.”

The overlapping and ever-expanding appetite of government and commerce to keep tabs on us— and our own appetite for keeping tabs on one another— means that it’s virtually impossible to elude our own autobiographical trail of purchasing habits, property ownership, employment history, credit scores, educational records, and in my case, a security clearance record a mile long.

What have you added to your trail today?  Are you sure you wanted to do that?
