This is an interesting point. The Justice league looks to be the same age. I'm going mostly with Batman since he is in that still with Nightwing, who looks to be doing the explaining thing. (But maybe he's actully leading the team, and replaced Batman as the guy who gives them their missions? Argh, why you do this!)

Miss M's age thing could probley be explaned that martians age/mature slower than humans. Superboy is a little harder to explan- clones age slower? Kryptonians age slower? Not mentally mature? Stayed on team to be with M'gann? Hmmm.
