Some medical analogies are easier to create than others. Ruhl has found that providers can easily come up with analogs for cholesterol, such as "high cholesterol is like hair that clogs up your drain."
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.
