I'm 15.  I know this one guy in my guild is 54...I was shocked because the way they talk they seem like they are in thier 30's.  haha but yea just thought I'd shard.  Also one of the people in my guild that has a 70 druid is 10...that makes me feel like I should quit seems my main is only 47 atm XD lol.

funny thing...many people in WoW seem to be younger than they really are, while others more mature...and a few act their own age...i guess you really are as old as you feel :)
