A lot of Facebook users may lie about their age to make them seem older than they really are, but 104-year-old Marguerite Joseph has had to do just the opposite on the social networking site: she lied about her age to make her seem younger.

Because of settings established by Facebook engineers, the 104-year-old grandmother has to say she's 99 to use the site.

"I was actually born on April 19, 1908," Joseph explains on her Facebook profile, "but Facebook wouldn't let me enter in a date that goes back that far."

Representatives from Facebook addressed the issue are are looking for a solution. 

"We've recently discovered an issue whereby some Facebook users may be unable to enter a birthday before 1910," a Facebook spokesperson said to Digital Life. "We are working on a fix for this and we apologize for the inconvenience."

The net-savvy grandma started using Facebook at the age of 102, the website said. "All of our family members always asked how grandma was doing on my Facebook page," said Joseph's granddaughter, Gail Marlow, according to the report. "So I decided I would set up a page of her own so she could stay connected to her family in Canada." 

Marlow operates her grandmother's Facebook page because the 104-year-old is legally blind. Marlow reads all of her messages to her, the report stated.

"Every time I tried to change the settings to the right year, Facebook always came back with an unknown error message and would send us right back to a year she wasn't born in," Marlow said. "I would love to see her real age on Facebook, I mean in April she's going to be 105. It's special."
