There once were a people who weren't exactly people at all. They had one head with hair, two eyes and ears, a mouth, tongue, neck, torso and abdomen, two arms with upper and lower sections both connected to hands with ten fingers each, two legs also split into upper and lower sections each connected to feet with 10 toes each. These people looked very much like, well, like people you would call people, at least from a short distance. Go back and read sentence number two. If you were to draw a person with these outward characteristics, and these outward characteristics only, what would this person be “missing”? If you read correctly and can draw a stick figure worth its weight in lead you’d notice neither nose nor nostrils upon your beautiful piece of art. Neither did these people have noses, or nostrils or lungs at all. To dissect one of these people would leave you wondering even more just how they could live and survive among us since they had no heart, no blood vessels, and no bowels. Your experimentation would show a very hollow body indeed, that is, if you had found one that hadn't eaten recently. You’ll notice that much of this story so far has been in the past tense, as in, these people no longer exist. If you stop now, then they never truly will have existed at all. Just think, you have the power to terminate an entire species of people by merely turning your head or scrolling away from the words you’re currently reading! Since you've decided against genocide for the time being, let’s continue to learn about this peculiar bunch of people creatures. As any living organism needs oxygen and nutrients to exist, so these people supplied themselves the same. “But they have no lungs!” You may protest. “But they have no way to deliver nutrients to their bodies!” You may exclaim. Which of your cells requires lungs or bowels to maintain its functionality? Your lungs and your bowels may help, but each cell individually has no need for any of this profligacy, neither did this people. Their hollow bodies made much more room for oxygen storage, consumption, and use by each of their cells. From this factoid alone you surely could understand how they made use of nutrients. They could ingest food, or even absorb nutrients via osmosis, or diffusion by rolling in the dirt to give their bodies the nutrients required. Once again, read sentence number two. Look at your drawing. Ask yourself “what happens after they gain all they can from a nutrient absorption?” Sentence two mentions no anus, or ureter, urethra, or way of expelling waste. This is because for these people, waste did not exist. Growth was perpetual. Even if something did get in that was of no use to their bodies; they would simply vomit or diffuse it from their flesh.
