I would have said that "yes, I think the DS's are way old", but Wendy's age has been openly stated. Unless an error by Hiro, I don't see why Wendy wouldn't be under the same conditions as Natsu and Gajeel. So, that is why I think they aren't that old, but they contain parts of their dragon teachers that made the barrier judge them as old...
