"Ignorance can be a blessing"; "Time can heal everything" -What if this doesn't apply to you?, in a human's life forgetting is a blessing, and ignorance the only reason we can be happy.. if not, then, how can we live happily if we don't ignore/forget the fact that we can die tomorrow? If you lack the capacity of forgetting, and your brain can be primed any second bringing out unwanted memories, can you truly be happy anyways?
