Of course, you didn’t choose your own name and you’re pretty much stuck with it unless you want to do something really radical and change it to one that sounds young. Like what? Josh or Jessica, if you want to go thirtyish. Hey, but those names are aging fast, so you may want to go even younger, with a name like Justice or Jagger. Or turn the whole age-name thing on its head and pick a really old name that’s popular for babies: Moses, say, or Matilda.
