People pondering the age-old query of "how old do I look?" are finally getting an answer, for better or for worse, thanks to a new website that's gone viral.
Developers at Microsoft launched a website this week that claims to guess a person’s gender and age based on a photo upload.
Corom Thompson and Santosh Balasubramanian launched the website, How-Old.net at a tech conference Thursday, not knowing it would go viral.
"We sent email to a group of several hundred people asking them to try the page for a few minutes and give us feedback - optimistically hoping that at least 50 people would give it a shot," they wrote in a blog post.
But within a few hours, they wrote they had already seen hits from more than 35,000 users from across the world.
While the answers are far from 100 percent accurate, many people are taking to social media to share the "age" guessed by the site.
