When your Google searches start giving away your age

In light of the recent changes to Google's privacy and a recent episode of Wait Wait Don't Tell Me I have been thinking about what my Google search activity says about me. Let's take my last few searches: "how to clean tile grout on your kitchen floor", "when can babies eat yogurt", "Baby Story Time", "Where to buy blank board books", and "Cornwall, England". What do these searches say about me? Well first off that I am boring, I dont go out to eat fun places (although we did go to Chick-fil-A today and it was delicious), and movies and concerts- oh please I spend my money at Costco, Hobby Lobby, and on baby stuff. Yeah, if Google was guessing my age and gender based on recent search activity I bet they'd have the gender right, but age, well they might be off by a decade or so.
