Since the PT came out, the Obi Wan duel has bothered me even more, not because of the choreography, but because we are to believe that Obi Wan as a character is in his late 50's when he is killed on the Death Star, yet Qui Gon Jinn is supposed to be around 60 years old in TPM, making them close to being the same age when they died, yet Qui Gon's dueling looks much more convincing. To make it even worse (for me anyway), Count Dooku is supposed to be in his 80's during AOTC and ROTS! I won't bother with Yoda, since he's an alien and his species is mysterious.

 

 They're ALL aliens, as far as we're concerned. Granted, human-looking characters in the Star Wars universe are subject to most of the same physical limitations as the rest of us (making all the arguments about unnatural movement perfectly valid), but who's to say the same rules of longevity apply?

Anyway, their 'years' most definitely wouldn't be the same as our 'years'   ;-)
