"Laugher is like "internal jogging." It temporarily increases your heart rate and blood pressure, followed by muscle relaxation and a decrease in blood pressure."
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.
