Interestingly, if you judge by their behaviour and looks, you'd say many of the heroes were older.

The senior X-men (Logan, Summers, Frost, Ororo, McCoy) and most Avengers seem to be in their late 30s / early 40s

Colossus, Gambit, Ice-Man, Spider-Man seem to be in their late 20s / early 30s

Magneto seems to be in his late 50s, maybe 60s

Richards and Doom seem to be in their 40s, as is most of the FF (apart from Johnny, who seems to be in his early 30s)
