that's what i would think..but it depends on how damaged his body is..but that seems to simple. I don't know, cause Fiege did say there are things we wouldn't pick up on until multiple viewings, and the whole hijacking thing, and tony hinting at himself maybe taking extremis, and the fact that the whole movie was in fact a memory of an unstable tony stark, would lead me to think there is more going on...the theme of this movie to me seemed like what extremis can do to the mind...think about it, stark handled is panic attacks, he had a complete character arc...so..WHY is he seeing a therapist if he sort of leveled out? He must not have, there must be something going on in his head, that, and the fact that the movie is his recollection makes me think there is more going on, and it hints it through out the movie, and THAT is what I think fiege was referring to. hence my deliberate attempt to think way outside the box.
