In the new issue of Captain America we learn that Steve Rogers is 40. I always found it a bit strange when we get to know the exact age of a character, as time works somewhat strange in the Marvel universe. I read this book in the 70ies, and what happened then clearly reflected that time period. Still, we have to ignore such things, as the characters hardly age at all, and then knowing the exact age kind of screws things up. Another paradox is Peggy Carter who was supposed to be Sharon's older sister and Cap's girlfriend during the war, but when she passed away, she was Sharon's aunt!
I remember while Byrne wrote FF many years ago, we saw Reed Richards celebrating his 40th birthday, meaning that he's probably in his early 40ies now. Are there any other characters were we have got to learn the exact age?
