DC and Marvel should stay away from ages unless they are actually willing to like their characters grow.
How old should Magneto be now if his WW 2 origin is still in place?
He should be 90 but Captain America/Wolverine/Red Skull/Thor/Exodus are older by decades to hundreds of years. Magneto was de aged and can't be more than 35 if the writers kept up with their own continuity and had better artists.
