Today I am grateful for indoor plumbing.
It seems that before indoor plumbing, there were a few unsavory options.
Option A: Poop in a pot in the corner of your room, throw it out of the window later. Problematically, you have to deal with poop smell in your room, then outside of your house.
Option B: Go to an outhouse. Because everyone wants to get up and go outside in the middle of the night when it is pouring rain and freezing cold to pee.
Option C: Dig a hole. Yeah, how about we not go there?
It is so incredible that now we can go to a specified room in our residence, take care of business, and push a button.
