If you time slipped 30 years, and were stuck, what would you do?
So time slipping is when you find yourself suddenly in a different era. It's been documented. Normally it fades back to present day (glitch in the matrix sort of thing).
But let's say you get stuck. You have 30 years of knowledge in your head. Are you going to do anything? Buy apple stocks around 1996? Invest in google? Stop 9/11 or at least set up a HD camera to see what really hit the towers?
What about stopping crimes? Or tragedies? Would you stop Diana dying in the Parisian tunnel? Stop Michael Jackson from hiring that quack who killed him?
Or would you just let things be as they are and not want to screw with anything?
