"Active immunity is like making a pie.. Passive immunity is simply buying a pie. The end result is the same whether you make a pie or buy it, but with active immunity, ? is gained, and immune products can be made over and over again."
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.
