[ WP ] The entire world suddenly and inexplicably goes back in time by 30 years ( including reverse aging ) , but everyone remembers what happens in the future , giving them the opportunity to make different decisions .

As of January 1st, the year is now 1987. The calendar should have moved forward to 2017, but nine days into the year, the world has now realized that 2017 will not happen. Not for another three decades. 
 
 
 It's 1987, the year of Whitney Houston and U2, Cheers and the Golden Girls, Lethal Weapon and Dirty Dancing, we also remember the warnings we had about Global Warming, genocides in Africa, the Middle East, South America and even Europe, about the ending of the Cold War and the beginnings of new and endless wars presented in ways that would make George Orwell shiver. 
 
 
 They say that those who do n't know history are doomed to repeat it. I am a historian. I have spend my life studying the past and now I find myself repeating it. The whole world is repeating it and we all remember. Every last one of us. 
 
 
 And yet, buried in the back of the newspapers ( because newspapers are a thing again ) buried under the news of this mysterious time travel the entire earth has experienced, I can see it. There are still reporters out there. In factories that still fire up and shoot ozone depleting emissions into the air. In Rwanda where the Hutus and the Tutsis fight once again. In South America, where President Ronald Regan is accused of funding missions against democratically elected leaders. 
 
 
 We have been given another chance. But we will refuse to take it. Humans never change. And even if we know our history, we are doomed to repeat it. We've been given a chance to make 2017 a year in which we transcend our petty and violent natures. But when 2017 finally does come, if it does come, it will be just another fucked up year.
