I know how old the character is if you're speaking in terms of he was created in 1938.
What I mean is, how old is he in comic books currently, what age is he supposed to be? I know they're kind of coy about that.
I fear I've reached that dreaded age where I'm older than Superman and that leads to some complicated feelings. I could handle being older than other heroes, Wally West for example, wasn't that weird. But its going to be weird being older than Superman. He's such an adult. At least with Wally it was like "I'm older than Wally, but I'm also more mature than Wally." But nobody is more mature than Superman. How can you compete with that?
I figure I was older than New 52 Superman, he struck me as being in his late 20's. But Rebirth Superman is clearly older.
