One moment that you could recapture for one moment. A fleeting moment. For one fleeting moment you could relive one past moment. You couldn't change anything. Just re-experience it. Not merely think about it or dream about it but be there again one moment for one moment.
Would it be to say good bye again or meet for the first time again. Or witness the birth of your child again. Your first …fill in the blank.
You were granted the gift to redo one moment for one moment.
But now the more intriguing question…once you experience that moment for a moment would you be different now. Would you be more grateful now. Would you live more gracefully now. Would you chill out and appreciate what is now because of the revisiting of the moment for a moment.
If so, then time travel and relive it so you can move on now in a better way. A more complete way. An ageless experiment.
