Some more than others. [Considering that Tony didn't make it 24 hours after his battle with Obidiah before announcing his superhero status, it's a fair statement.

Not that he doesn't still try to hide things. But that's more personal, in Tony's case.]

Honestly, I think that's one of the things people could probably drive yourself insane trying to figure out. Especially here, since we don't have any way of really knowing. It's all speculation, that we probably won't even remember.
