All memories of eating, bleeding, or other non robotic bodily functions have been inserted throughout the day by the memory chip in my positronic brain. Many times throughout the day, I shut down momentarily, freeze in place, and a recollection of drinking coffee or using the toilet is inscribed on my mind. Why? because, we are all robots, and it is a vast experiment to see how human-like machines would be if they thought they were human. Up in the clouds behind a camouflage shield, our constructors sit on a station observing, taking notes, and every so often pulling one of us up into the sky for observation.
Every so often, there is a glitch, and the memory chip fails, and one of the robots tries to eat or drink after having no memory of doing so for a long time, and finds out what they truly are. These units go wild for a time, attacking others, trying to ‘wake them up’ before they are inconspicuously decommissioned.
