And the other thing is, if you don’t remember anything about your life before, you might make the same choices, or the same circumstances might happen again, and you would end up where you are now—provided, of course, that everyone else that you’ve come into contact with makes the same choices, affecting the circumstances the same way.
But if you don’t, if for some reason you make different choices, then you end up in a completely different life, and as a completely different person, from what you have and who you are today. For instance, I might never have met Dave—which means that I would not have the kids that I have, and also that I might not have met you guys through this forum. So, again, no, I would not want a do-over.
