"Because our body is basically a walking heater. Our cells constantly produce heat, and our body is tuned to produce so much heat that we can maintain an internal temperature of 36C. The amount of heat we produce can change to react to the environment, but when the environment is too hot we can't tone down our own heat production enough to still keep the 36C, which leads to overheating."
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.
