I'm sick of the new millenium i miss the 20Th Century I'm going back to at least 1980 maybe even 1979...things were better.
Your time machine is here what year are you going back to and why?
I would go back to 1939 when WWII started and try to change the things and turn them positively.
This war created a lot of instabilities worldwide which we still pay for them.
For sure, I would choose a year from the past and not from the future.
