Answer:
All ages.
----
Jason earls < for example > is 29. i know... its hard to belive but its on his imdb page
Ummm.... I really doubt that's he's almost 30, he doesn't have the mature features that a man of that age would have, Are you sure it wasn't like 20 or something?

if you go on imdb.com and look up Jason earls, then you look for his birthday year on there and you can see if im telling the truth or not!
^^ they're right I've had this debate before. he was born in 1989.
