The same goes for the age. Tony Stark has been as old as he is ever since he was introduced. Spider-Man started off as a 15 year old teenager. He is one of the few, who has progressed. Now he is 28-29 and that's his modern status quo. Tony Stark on the other hand hasn't aged 15 years. Neither has the Punisher, who started off as a Vietnam veteran, but now his backstory has been retconned to being an Iraq veteran, so that his age makes more sense. I don't think that someone like Cyclops is 45 years. He might act more mature, but his status quo is probably him being in his mid to late 30s.
In DC you have the same things. There were times where Batman and Superman got quite old. You could say that they were in their mid 40s. But their new status quo is probably more like 29-30, where other characters have absolutely aged. Like Nightwing, who started off as a very young Robin. Same with Red Hood. Even Tim Drake got slightly older, so that Damian Wayne could be the new young Robin. But those age changes didn't make Batman 60 years old.
You just have to roll with it.
