If you could go back and have a do-over on the 100 dumbest things you have ever said, would you do it?
If these uninformed or thoughtless statements fell under the headings of insensitivity or hurtfulness, you might be able to undo some serious wrongs.
Or if the remarks you would erase were simply moronic, you might be able to reshape and improve your standing with friends, colleagues and loved ones.
But haven't we learned from science fiction that tampering with the space/time continuum can have unintended consequences?
Maybe something you said that was blazingly stupid led to a chain of events producing an important, happy outcome? You never know.
Of course, mulling this time-travel exercise requires that a person be capable of considering that perhaps not everything he or she has uttered was brilliant. Not everyone could admit that.
