Were you aware that Google has been monitoring everything that you do online, and they are using that information for the companies gain? But, how much do they really know? Have a little fun and see if they guessed you your age, gender, and interests correctly.

In order for you to find out what Google knows, or thinks it knows, about you, just go to your ad preferences manager within your Google account. Or, to make it easier for you, you can just click here -- if you're still signed into your Gmail account, you won't even have to sign back in.

How much of your personal profile did they get right? Maybe we should all think twice before we Google again, huh?
