The Internet giveth and the Internet taketh away, and somehow it's managed to do both at once with this completely addictive and potentially ego-crushing new game.
Microsoft's new site How Old Do I Look uses “state-of-the-art, cloud-based algorithms” to recognise human faces and guess their age and gender.
But the results are not always accurate...
Thanks to some hilariously unflattering guesses, an online frenzy (and potentially skyrocketing sales of eye cream) has ensued since the game's release on Wednesday.
Microsoft engineers Corom Thompson and Santosh Balasubramanian blogged that the site was initially only launched as to be a small test for 50 people invited by email, but within a few hours received hits from over 35,000 users all over the world.
Today has seen our social media feeds flooded with screen shots of How Old Do I Look results of friends, celebrities, pets and even inanimate objects, with ages ranging from spookily accurate to downright ridiculous.
Here's what happened when some brave HuffPost UK team members tested it out:
