blood circulation
"Let us take a moment to discuss what the kidneys do. In several of my previous columns, I use the analogy that our blood circulation is like plumbing with the heart being the pump and the arteries and veins being the pipes. Well, the kidneys are the filter and the drain, which create urine as a way to expel waste products from the body."
"Your body's blood circulation is like your cash flow. If you have a very slow cash flow or infrequent supply of cash you may feel stressed about meeting your financial obligations. You probably always feel poor. In the same way your body requires constant supply of fresh blood to carry out daily activities. Without a constant flow of blood, your hands and feet will always feel cold and you will feel lethargic. Acupuncture can help stimulate the body's circulation to reduce the symptoms mentioned above."
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.
