I became aware of my mortality before we had a dining room table. I don’t recall the exact age, I only know the arrangement of furniture, and the dining room then was just an empty space to play in. I can tell you that I was five or six and no older than that. Six however is a world apart from five when you’ve only existed on earth for that many years. And this must have had something to do with it; the realization of how long I had existed. To realize your existence is to also become suddenly aware of how long you have not existed. Of course I had not existed for billions of years before my birth, but that’s too much time to handle, so my brain measures things the way it can. It makes do. I measure time against my parents, my mother most exactly, so for five years I had existed, but for twenty seven years before my mother gave birth to me, I did not exist.
