While there are many time periods that I'd love to visit, such as the 1930s and 40s for its style in vehicles, clothes and beauty standards, I feel that the time period we are in right now is still preferable. Not ideal, but preferable. While a visit may be charming, actually living in another time period may be very difficult for someone from this one. The notion may seem romantic, but the reality is quite different.
However, to quote Dr. Emmett Lathrop Brown, Ph.D., "where are we going?" Is in my opinion the most interesting question -- we know where we came from, but we don't know where we're going. I'd love to jump forward a few decades and see what is happening. At the same time however I feel that living in the future may be just as difficult as living in the past, for the very same reasons.
