Going back in time seems like it would be pretty miserable for anyone who is blessed with 21st century technology and comfort. I can still remember not having indoor plumbing (yes, I'm THAT old), no air conditioning, one old un-air-conditioned car that had to be worked on constantly by my dad, no TV. Going foward in time seems like it might be OK. As long one would be able to come back. So collect some world series and super bowl scores, stock prices and powerball numbers from the near future and come back. Automatic easy street!
