Someone very mysterious looking walks up to you and hands you a box with a button. He tells you that whatever moment in your life you're thinking of when you press it, you instantly go back to that moment to try again. You'd retain all your memories from the future that hasn't happened, but your body would return to it's previous state.
Would you use the button, risking the person you are now to possibly be someone different?
EDIT: EDIT: Poll fixed.
