Maybe someday we will have that option on our phones or laptops, to 'exit/reload/replay'. Like mini time machines, ones that will only go back, say, one hour, or maybe a day. Like setting an alarm clock or something. Don't like the outcome of a personal decision? Replay it, until you get it right!
Of course, that would only be if we are masters of our own fate, and nothing is predestined.
Come to think of it, we are not masters of OUR own fate, but masters over other people's fates as well, to some extent, because, other than minor things, like taking a shower or deciding what to wear, most everything we say and do can and does affect others.
Yeah, I suppose it would get pretty messy if everyone, at the same time, was adjusting their lives, too. Probably would be complete chaos.
Scratch that idea. *sigh*
