K. So let's get a few obvious ones out of the way, Bruce Banner is younger than Tony Stark, I think he's 30-40, so he probably started his tortured career a little after Tony.

Mr. Fantastic is one of the oldest heroes (that's why he's sometimes seen with white stripes in his hair) so he probably started before all of them, he'd be probably in his very late 50s, so that means the rest of the FF would probably be 30-40.
