Unlike a lot of prequel excuses made by PT fans, THAT doesn't require a freakish amount of stretching or distorting. It's plain, simple, and believable. Don't act like it's not.

Whoa, didn't mean to step on your toes.

I'm not acting like it isn't plain simple and believable, too me it isn't. Too me it really seems like as dumb of an explanation as "Grevious' lungs must be someplace else..." or any other explaining away of PT gaffs. Nothing personal, it just is what it is.

I have known some people who lived some very stressful lives, and sure, they look a little worse for wear but they don't look like seventy year olds when they are only fifty. You can seriously imagine someone going from looking like Ewan McGregor to Sir Alec Guinness in the course of 19 years just because of some stress? It is great if you can, but to me that is a pretty massive stretch. Again, nothing personal.

Besides, Old Ben Kenobi who lives out by the Dune Sea that we meet in the first SW film has always struck me as kind of a laid back guy, not a hand wringer. If he was so worried about Luke's safety, I am sure he would have sent him to Yoda sooner (like as in, before he was "too old" to begin his training), or taken the time to have the kid's last named changed to Lars, or left him with someone other than known relatives, just in case Darth hears that his step brother is raising a child with the last name Skywalker and begins to ponder if there might be some kind of relation. No, everything we see of the old man in the OT shows us a guy who has things under control, not a worry wart who suffers from extremely excelled aging. As for the twin suns, nobody else on the planet seems to have a hard time with them.
