Lotus-Eaterology:
A field pertaining to the study of lotus eating. Eating the narcotic lotus plant is said to induce a peaceful, apathetic, dreamy, and languorous state of mind and being. In Greek mythology, Odysseus and his crew happened upon an island of "lotus-eaters", some fell into the ethereal trance of the lotus but Odysseus forced them to swallow the hard red pill and dragged them back to the ship of reality.
