Don't be swayed by age group. It's about the individual. A friend's mother blogged practically up until she died at age 92. I occasionally helped her out with her Mac, and she was always interested in understanding how I was doing what I was doing.
Swayed? Huh?
There are exceptions to all rules, and your friend's mother sounds very much like one of them.
I mentioned AARP because I believe its magazine has got the largest circulation of any publication in America; if FTM could finagle even a mention, the exposure would be enormous.
