There’s a lot of effort on the part of some juveniles to fabricate fake IDs for purposes of buying things, or gaining entrance to events, which are reserved for adults. I question whether this is actually the best route to take. I would imagine that the negative consequences resulting from exposure of counterfeit ID fabrication are more serious than if it were discovered you were physically trying to pass off as an old man. An additional plus is that this latter method would only require the acquisition of a makeup kit and a few minutes practice with rough voice duplication.
