Ha, so true.
Although I wonder if Raven might have inherited some longevity from her dad. It would be snarky fun if she appeared in the 30th century or whatever, and was still a teenager... (Or, even more oddly, appeared in the ancient past, and was an eight year old, or something, and it was retconned that she's been banging around some combination of Earth and Azarath for thousands of years, and it's taken her all this time to become a teen!)
