brushing and flossing
"Brushing and flossing is like peanut butter and jelly -- when you think of one you can't help but think of the other. It may seem tedious, but flossing every day is one of the best things you can do for your oral health."
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.
