Banner is another guy. Does human Banner show signs of aging or does the Hulk prevent that? I don't know if comics provided an answer to that.
10 years of in-movie time? I have absolutely no clue. I don't know that the MCU will even cover ten years of time. If it does, Colin Farrel might be too old to play a superhero by then if they keep up the rate they're going. Oddly, Banner does seem to have aged quite a bit in the few months between TIH and Avengers. But you bring up a good point. This generation of stories may not be long enough in-universe for any given character to necessarily show signs of aging. But, if they do that, that would require recasts so that the characters don't appear to age at some point. Interesting.
