Anna Stoehr, 113, using her iPad with KARE-11 reporters KARE-11

Anna Stoehr is tech-savvy for her age of 113. But though she can use FaceTime to chat to her 85-year-old son and search Google for whatever she wants, the silver surfer hit a snag when trying to sign up to Facebook.

The woman, who is the oldest person in her home state of Minnesota, was not able to choose her birth year - 1900 - from Facebook's drop down menu on its 'join' page. It meant she had to fudge her real age and shave 15 years off until she was a sprightly 99 years old, according to her social network profile.

The earliest date users can choose from is 1905.

According to The Daily Dot, Stoehr used her typewriter to send a letter to Mark Zuckerberg, owner of Facebook, in which she wrote: "I'm still here".

Facebook last year changed its minimum age for users to 13, but it is reported that pre-teens are able to lie about their age and pretend to be older to get access to the site.

Stoehr's story - which falls squarely on the opposite end of the spectrum - is one of the tales in news channel KARE-11's series Boyd Huppert's Land of 10,000 Stories.
