You'd appreciate the classic (possibly apocryphal) story of Sir Isaac Newton, then, who notoriously forgot to eat, on a regular basis. One day, his housekeeper (part of that supportive social network!) decided to play a practical joke on him, and, while he was deep in thought, placed a dish of chicken bones in front of him. Much later, he emerged from contemplation feeling slightly peckish, and asked for some food, at which point she indicated his plate of chicken leavings and told him he had already eaten--which he believed, as it was consistent with the available data!
