Creative people are very insecure people because they don't know whether people like them or are in awe of them. That insecurity always comes out. It makes them a better actor, I feel.
If you don't physically age gracefully, it's a bit sad. I think Steven Tyler can get away anything, because he still looks like he did in '73. Especially from row Z backwards in an arena. As long as the Stones keep their hair and don't get fat they'll get away with the wrinkles.
