"A stroke is like a "brain attack." In a heart attack, not enough blood gets to the heart. In a stroke, not enough blood gets to the brain. Parts of the brain can die during a stroke if blood is cut off for more than a couple of hours. If the blood is cut off for a shorter time, stroke symptoms like weakness, numbness, or trouble speaking may clear up within a few hours. This is called a transient ischemic attack (TIA), rather than a stroke. "
"A stroke is like a small part of the brain is drowning, and if you don't re-establish blood flow within a very short period of time, part of the brain is irreversibly damaged,"
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.
