REWIND BUTTON, ANYONE?

Greetings, Cool Peeps:

You know, there isn't a day that goes by when I don't think about how technology has vastly changed the way we do everything. I won't even try to give a brief mention to everything (both positive and negative) that has come from a recent technological advance. So, I just have one question: with all of the "stuff" that has been invented, why hasn't someone figured out how to make a rewind button?

Do you know how many miserable situations could just be avoided if we could ...
