[http://enterthestory.com/comics/realtime_marvel_1960s.html Back in the 1962 we were even given the characters ages. This is by Stan Lee from an early letters column]:
 * "Mr. Fantastic and Ben Grimm are both in their late thirties, having graduated college when they were very young. Sue Storm is in her twenties, and Johnny is just seventeen. (We can't tell you Sue's EXACT age because, being a female, she'd never talk to us again!)"
