Still hard to accept yes? Look, I made it here for you. You may call yourself fatter, older, taller now because you have a memory of your previous state? Lha if you do not remember anything how try it?
Okay for example you document in the form of photos or diburn on dvd media. If you do not have a memory, yes you are still confused. This is who is it in the photo? How come this dvd can ya? Who documenting it huh? You do not even know what your name is.
When you do not have the ability to remember everything you learn, it always goes away with no trace. So back again to the explanation above. Time is about comparison !!
