Yeah, I hate how they seem to forget that characters with longevity would most likely age proportionately. Yoda looked like a young... er, man, in TPM when there really shouldn't have been that much change to him. And I hated in the Sith documentaries how George would give his stupid chuckle and say that Chewbacca was the junior league. He was 200 years old in the original movies! Nineteen years for a lifespan like that wouldn't make that much of a difference! It just shows how little thought George puts into his own characters.
