What PQ said.
Not sure I agree with Green Cloud though. I did some hung gar for 7 years and needed every bit of athleticism I had. heh, I just got my ass handed to me by that same teacher a month ago...some things never change.
Any good teacher of any style should be able to understand and work with any age induced limitations you might have. Though, it doesn't sound like you really have any. No, you probably won't be doing 540 or 720 jumping spin kicks but do you really want to train TKD or Wushu?
some say it takes 10-15 years to learn a system but that's just the basic mechanics I think.
But, what are you after? Answer that and then go looking for a teacher who can help you meet that and don't worry about style so much.
good luck.

"Is enlightenment even possible? Or, did I drive by it like a missed exit?"
It's simpler than you think.
I could be completely wrong"
