I would like to live at all times, like Duncan MacLeod, to know all truth

More or less I think I'd also choose the century german_dude has chosen; and there's quite some reason for that. I wouldn't ever want to live in a century where there is no washing machine; neither in a century which has diseases like leprosy and tuberculosis. Nor in a century where I have to carry water from a spring 2 miles away from home. I love pressing a plastic switch on the wall and filling my chambers with light. I also like to turn a dial on my radio and instantly hear an orchestra playing for my majesty from the other side of the world for less than a penny. I guess Vivaldi would be jealous for such a comfort! I love to be able to press a button and chat with my brother who lives 2000 miles away while he's in the train, on his way to work and see his face. Most of the facts I've mentioned above have not been available, not even to the richest people before the 20th century. Now, if I can have all that plus be able to ride a 'ship' which floats on the ionosphere, and feel the euphoria of accelerating a few thousand miles per hour in orbit and reaching a 0.6g gravity, that would be another thing I would call progress. Although there's always the possibility of getting a speeding ticket from the heavenly police :( But nothing of that all is really worth if the society surrounding me is filled with greed, evil and criminality.

The 20th century, if I get to choose the country. This one may very well be the final one and who wants the bother. People keep telling me they'd like to live in the old days - much before 1800. They get all romantic about it. Actually the history of mankind much before now was the same - a small elite living well off the work of a large majority of workers or slaves who were continually in misery and on the edge of starvation. Every one who thinks they want to live in such a bygon era always thinks of themselves as a member of the elite. The chances are much greater that they would be living in abject poverty. No thank you. I once had someone tell me they would have loved to live in ancient Athens, at the height of its glory. My reply: "Oh, you want to be a slave? Because the majority of Athens' inhabitants were slaves, not people like Socrates and Plato." [Sorry for the rant. I have to control myself more]

If you have the chance, in which century would you want to lıve? In the final one. ;)
