My biggest personal fear is the "history of depression" one, because I can plausibly conceal it (in fact, there are a number of laws to help me in doing so).
My standing question for the last several years has been "if we know absolutely everything about absolutely everyone, will some taboos disappear?" Depression is vastly more common than some people think, and if we're going to lose all privacy it'd be nice if we understood each other a little better.
