Oh. Riiiight~~ I completely forgot about that--probably cause the movie didn't really bring that across really well--Stark was pretty buff for a guy with an artificial heart, so I kept expecting him to be more skilled. Plus, I'm not very familiar with the original comic character. ///^^///

It was nice to see him harden after the kidnapping though--from softly skinny in his playboy days to hardened muscle post-kidnaping. The physical change reinforced his psychological one.
