exercise
"Exercise does the same kind of thing that many of our medicines do. A bout of exercise is like taking a little bit of Prozac and a little bit of Ritalin"
"Think about it this way: if weight loss is like a journey, exercise is like shoveling out your driveway before you leave. It's necessary, but it's not enough all on its own."
"Exercise is like a savings account. The more you put in, the more you're going to get out of it."

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.
