There are any number of reasons that one may want to change or update one’s age and birthday information on Match.com, including that you accidentally entered the wrong date of birth when you signed up, or that you intentionally put the wrong birth date (particularly the year) in order to ‘trick the algorithms’ (which is the excuse that most people give when they cop to having lied about their age on a dating site). Whatever the reason, if you now want to correct your date of birth on Match.com you may find that it seems impossible. But it’s not. Here’s how to update your date of birth on Match.com.

That Microsoft website that guesses your age, how-old.net (hashtag #HowOldRobot ) is actually a cleverly disguised system designed to grab your metadata from your photos so that it can be used to advertise to you. Some of the data that how-old.net has been grabbing while guessing how old you are includes your gender, your age, and your location (along with your User Agent string). Exactly the type of data they need for targeting marketing.

Turns out there is another reason for rejecting all those insidious game invitations from smartphone apps and their Facebook counterparts: the New York Times has revealed today that the NSA and its British counterpart, GCHQ, are mining the data that your smartphone apps are generating, from location data, to contact lists, to phone logs and even the data embedded in images. Dubbed the “Mobile Surge” by the Brits, the intelligence community is giddy with glee over the trove of data served up by mobile apps.
