I am so smart. S-M-R-T -- I mean S-M-A-R-T

I just thought of something, something that is I think is briliant (but that could just be my lack of sleep talking.)

In Marvel and DC comics, events are on a 'sliding time scale'. That's how they explain how the characters never age.
For example, the Fantastic Four stole a rocket and blasted into space on that fateful day back in 1961, which led to them gaining their powers by cosmic rays. Except it didn't, now it is considered that it happened only about 10-12 years ago (comic time). Time compresses and slides in continuity so that the events always happened more recently than they really did.
Also, Peter Parker was 15 in Amazing Fantasy #15 when he became Spider-Man. Now, 58 years later, Peter is still in his late 20's/early 30's. So what am I trying to get at here? What if he wasn't? What if he was 73 right now?

I think it would be incredibly interesting if someone would create a comic book universe that moves (for the most part) in real time. Characters age a year every year. You have new heroes introduced, old heroes retire/die and everything all flows like reality. I don't know why, but this idea facinates me. And I'm not talking about elseworlds miniseries, Dark Knight Returns type things. Their main Universe and continuity ages in real time.

Really, I think that'd be sort of cool.
