To be fair, a very large chunk of old people are likewise uninteresting. Aside from the general dulling of the mind that comes with age, you have to actually do things with those years for them to mean something.
Even if a person is a simple product of their times, as one gets older that gets increasingly interesting. Because the times change so much over the years.
"Middle age is the period of age beyond young adulthood but before the onset of old age."
"Meaning something" personally and "being interesting" are not the same.
Also there isn't that much wrong with just exploiting popularity machine. So a bunch of people thought you were a young girl, and you're not... who cares! If anything you are teaching people to stop putting so much credence into the SM sphere... which can only be good.
