Does Google accurately guess your age and gender?
No-one is probably shocked of google tracking their behavior and profiling them:
Slate: Does Google Accurately Guess Your Age and Gender? Find out what Google guesses is your age and gender. These “inferred demographics” are based on the websites you visit and are tracked by a Google cookie; they are used for advertising purposes Alas, Google was not able to guess my age and just resulted in “No interest or demographic categories are associated with your ads preferences so far” This might have something to do with with me blocking google ads, though I am surprised it does not use my G+ account details for the “demographics [sic.] estimation”.
