I would say getting myself into much better shape than I was in my teenage years, and early 20's. I'm quite proud of the fact I've managed to change my lifestyle and that I'm at where I now am, though there are days when I think I've still got a bit to go, but aside from a few achy joints, I'm fit, healthy, and it's something I'm maintaining.
If you could extract a period of history ... from history, and place it in the modern world (if needs be, overwriting the modern place) which period of history would you use?
Just an example; but lets say you wanted to bring forth an ancient Mayan or Egyptian culture, they'd replace the grounds upon the modern day natives - if that makes sense? Or I suppose, to put it simpler, if you could have an attraction where you can observe an ancient culture, or period of time, which would it be?
