I guess the age should not be something that distinguishes \"noobs\" from \"non-noobs\".
If you need advice how to play the game or control your character, there is the /advice command (or whatever it is called). Maybe it should be more advertised?
If you want to ask how to get somewhere or similar, just try. A \"noob\" might have accidentally gone there as the first thing they did in-game while an experienced player might have accidentally never visited the place you want to know about.
And after all, you can play a character that lived in his home village for 60 years, and then went to a city (for wahever reason) that is strange and unfamiliar to him.
So I think that the different chracter skins should also look of different age. That way you can choose age for your character.
Many problems of forcing all new characters to be childern and in-game aging were already mentioned.
Maybe you could have the option to age your character manually when you see fit, and buy youth potions as well.
