"Inflammation of a bursa. A bursa is like a tiny pillow filled with fluid between the tendon and the bone. It is not arthritis because it is outside the joint."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
