Where do you dream up 50 years? Guinness would have been like 11 years old. He turned 62 while filming ANH. Some people try to place him at much older. But that was his age.

I assume you're replying to me, correct? Well, not only did I say more than 50 years (54 if you want an exact number), I was talking about the age of the Empire, not Ben himself. Ben himself I imagine as having been born about six years before the transition. That would make him about 59/60 in the first movie, which isn't too far off from his real-life age at the time.
