[Norfleet]

Actually, you're really a brain in a tank being raised as a delicacy for us, your alien overlords. We feed you these sensations because if you are not kept relatively engaged, you develop a bad taste. At the same time, if you are allowed to become too happy, you become fatty and unhealthful. Thus, a certain level of trial and misery is required in your experiences, so that you develop the proper flavor when we pluck you from the tank and cook you. That's what really happens when you die of old age. There's no such thing as old age, really.
