"For those of you who don't know, a beta blocker is like a governor for your heart. It puts a ceiling on your heart rate making it nearly impossible for it to go above a certain rate."
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.
