How old do you really look? This website will tell you in seconds

  • Microsoft unveils site that tries to guess how old you are
  • Sometimes it's dead on, sometimes it's hilariously wrong

(CNN)You're only as old as you think you are.

Or in this case, as old as a computer algorithm thinks you are.
In a machine learning experiment that's taken social vanity to new heights, Microsoft has created a website that tells you how old you look just by analyzing your photo.
    Sometimes it's dead on. Other times it's hilariously, outrageously wrong.
    It's simple: Upload a selfie, wait a few seconds -- then the machine gives you a number.
    And since it can analyze anyone's photo, you can compare yourself to your friends, family, and foes.
    But guessing someone's age is a dangerous game, even for a robot. That's probably why the site comes with a sheepish apology. "Sorry if we didn't quite get the age and gender right," it says after each result.
    The company unveiled the website at a conference in late April as a way to show off its new software.
    Part of a new initiative called Project Oxford, Microsoft says you could use this face detection technology for tasks like sorting through a large photo collection.
    But we're human -- so we'll probably just use it to judge our own looks.
    And everyone else's.
