Who am I but my memories and thoughts. What makes me who I am, are the occurrences of the past. When I am born, I have thoughts but have no memory; but before death, I will have thoughts and so much memory. But what becomes of this memory when I die? As my brain waves cease, will all my memories be nonexistent like when I was born? But even without any memories, I may still be able to think. If I think, according to the great philosopher Descartes I would exist. Cogito ergo sum (I think, therefore I am). If my body and brain cease to function, where do my thoughts originate from; and if I exist where am I? But more important where am I going to?
