At age 105, Edythe Kirchmaier is Facebook's oldest registered user.
Kirchmaier, who is also California's oldest licensed driver and the University of Chicago's oldest living former student, joined Facebook last month. Direct Relief, a medical aid charity where she's volunteered for 40 years, set up the account in honor of her 105th birthday.
"I've been contacted by such wonderful people and received such nice messages and pictures from people all over the world," Kirchmaier said. "I'm so humbled by all the interest in me."
Born into the age of telegraphs and rotary dial telephones, Kirchmaier said she embraces social media because it allows her to check in daily with friends and family. She said she's especially interested to see how many people log on to light a virtual candle in her honor, a symbol they've liked the fan page of Direct Relief.
"I'm hoping to get 105,000 likes for the page," she said.
The page currently has 77,000-plus likes.
Kirchmaier herself already has more than 20,000 Facebook friends. She lists the University of Chicago, the actress Jane Lynch and the Cheesecake Factory among her "likes." Pokes don't seem to be her thing.
While the centenarian said she cherishes her Facebook relationships, she still believes in the power of the pen. Every Tuesday she heads over to Direct Relief's offices in Santa Barbara, Calif., to hand-write thank-you letters to the charity's donors.
"She physically writes the letters herself, and I think her handwriting is better than mine," noted Hannah Rael, a media relations associate for the charity.
Seniors 'Friend' to the End
While Kirchmaier is the oldest person on Facebook, she is hardly the only senior to embrace social media. The social site's demographics have grown steadily grayer over the past few years.
Retirees age 65 and older are the fastest-growing group of social networkers on sites such as Facebook, LinkedIn and MySpace, according to a 2012 survey by the Pew Research Center's Internet and American Life Project. The report found that 40 percent of Internet users older than 65 use Facebook, up 150 percent since 2009.
Golden-agers are also signing onto Twitter in record numbers. In 2009, only 5 percent of Internet users in the 50 to 64 age bracket had used Twitter, or some other status-update service. It's now up to 11 percent.
Kirchmaier said she didn't yet have a Twitter account but finds the idea of communicating in 140 characters or less intriguing.
"I just may give it a try," she said.
Seniors log on to social media to stay in touch, reconnect with people from their past and seek support for chronic health conditions, the Pew report found. A University of Alabama at Birmingham study suggested that Internet use was associated with a 30 percent decrease in depressive symptoms among older adults who used it regularly.
"One of the greatest benefits of social media for older people is learning they're not alone," said Kristi Grigsby, director of communications for the website ageingcare.com. "It helps them focus their attention on something other than being old."
"This is how I keep in touch with friends, children and grandchildren. ... I enjoy just checking Facebook every day and seeing the pictures that have been added and reading some of the messages. ... I still exchange emails with my high school friends and some of my former students. ... It keeps me from getting lonely," wrote one 85-year-old on an Aging Care forum.
