Either is acceptable; you'll find that 'aged' is more popular in the UK. 'Age' implies, "this person is age____," while 'aged' implies "this person has lived _____years." Basically the same thing. I prefer 'aged' because I'm pretentious like that. Go with your gut. I mean, who gives a rat's, right? Same ish.
