YES! A service to all of mankind!
I think I'd like to go back in time, but not to the stone age. Maybe to the 40's or 50's in this country. That seemed to be the best time in this country. I would be afraid of going to the future because of the shock. It seems cool on the surface to go into the future, but I wouldn't understand what they would be saying. Think about it, if someone from the '70's suddenly came into this timeframe and you asked them to Google something or asked them about the latest tweet, or about carbon footprints, ect. they would be lost. When you think of all the "new" lingo that we use, someone from even 20 years ago would be lost. I would hate to be the one who needed an explanation of things every 10 minutes!
