"YOUR search history contains some of the most personal information you will ever reveal online: your health, mental state, interests, travel locations, fears and shopping habits.
And that is information most people would want to keep private. Unfortunately, your web searches are carefully tracked and saved in databases, where the information can be used for almost anything, including highly targeted advertising and price discrimination based on your data profile."
