Allow me to talk number 2 for a moment. I bet some day will come the invention of the "smart toilet." It will read back to you calculations about density, mass. It will tell you things about your health and bowel movements based on pH calculations and how it corresponds with what you had previously entered into the menu database for the meals you have eaten. It will tell you when that pizza you had on Friday is fully digested.
Because let's all face it, it's human instinct to take a look at what we've expelled from our bodies.
I sometimes stop and think about what I've contributed to the sewer system over the course of the day. And that if we faced apocalypse and running water had stopped, convenience and grocery stores ransacked for bottled water, rivers dangerous due to people taking armed territory at sections, the sewer with it's dark river below us may become a last resort. I sometimes think about such a thing, and what sort of contraption I would manufacture with my own two hands and found objects to clean the water and purify it. It would perhaps take a lot of strainers and boiling to re-allocate steam, to more strainers and boiling to really get the shit out of it and avoid a stomach ache.
The sewer is a resource. And if never touched, 1 million years from now, what will have become of all of the human waste, dish water, detergent, bleach, cleaning supplies, Drano, dead skin cells, soap, shampoo, toothpaste, vomit, blood, fingernails, hair, motor oil, and a variety of other items, after having sloshed around and drifted down as gunk lining the bottom of the sewer floor. Will it become its own type of rock, caked layers pressed, that can be burned for fuel?
Sometimes I think these thoughts. Not as a fixation, just drifting what ifs in my mind at some points of the day. Shit worth thinking. Because shit is always happening all over the globe, slipping away below us to a story we rarely bother ourselves to imagine because it may be grotesque.
