The last issue of Invincible Ironman featured Tony Stark turning 35. That got me wondering. Does Marvel keep track of each character's age? 
I estimated to about 5 real years to 1 Marvel Universe year and back tracked Tony Starks life. I found that if he is currently at the age of 35, then in 1963, when Ironman was created, he was in his mid 20's. Which could make sense. 
I took that research and used it elsewhere. Spider-man, AKA Peter Parker was (im guessing) around the age of 15 when he became Spider-man. After i apply my research it seems he would now be around the age of 24 or 25. 
Recently, in an interview, the writer of the new series "Wolverine and Jubilee" said that Jubilee was 17 years old in this series. I backtracted Jubilee to when she first appeared in 1989. Twelve years old. If you do the math she would be around the age of 16 or 17, which makes sense. 
So yes, i do believe this company knows how to manage its character's ages. What do you think?

Sometimes I think they do keep track. Though I think they make it up on occasion.

I was sort of shocked when Jubilee said she was seventeen in that book. I mistook her for being at the very least 18. 

It seems to me that writers try to age characters slowly but also keep the times current. Kind of like the world around the characters is moving faster than the characters themselves.

" @doordoor123: This may have previously been discussed but another criteria to keep in mind is this when applicable to comics:  A single issue of a comic book, which normally gets published every month or every other month, sometimes can feature a story where the time involved is a matter of only minutes.  Heck, sometimes seconds, nano-seconds, or even no "time" at all, depending on the story.   It can also be about one day, a few days or a month.  So the time concept is drastically altered in the comic book universes at large, whether it involves Marvel or DC or other company.    So while Spidey appeared in the 1960's, in "real life" it was perhaps 10-15 years ago (  I know someone will correct me, ha!).  "

this is pretty much my exact argument when people complain about certain characters appearing in to many books "
