If you fell asleep one day and woke up as a Baby
Would you be sad? Sad that your present life is gone. That the people you know aren't there. If you have kids, they would be there.
Would you be Happy? Happy that you could start over. All the hardships would be gone. All the bad times you've had are gone.
Now you may have many questions. Questions like, would i remember everything. The answer is yes you would, but it would ask feel like a dream. And remember, dreams are sometimes forgotten. And you can't speak about them because we'll, your a baby
You just have to balance the choices. Do you have more to gain or more to lose.
