I hope this isn't too off topic, but I thought it could be answered here. :P In the first movie, they say that Anakin has a really high concentration of midichlorians in his blood, so he's supposed to be the most powerful ever. But in the commentaries for the original movies, George Lucas says that he's weaker because of his injuries (loss of limbs and stuff.) Wouldn't he be the same, though? I mean, just because he has less body mass, wouldn't the concentration be the same? I know it's a movie and all, but I was hoping there'd be a scientific explanation that made more sense.
