@shaneparrish Holy sh**! This just enligtened me that I'm storing all my stress in the stomach. I have literal cramps due to cortisol and adrenaline in the morning.
We didn't always use rectangles to plot land. This is a relatively contemporary practice. For most of our history we used methods similar to the "Metes and Bounds System". It relies on natural boundaries like rivers and landmarks like trees to mark the bounds of the plot of land.
"What is a straight line?" This question is so important to our intuition and civilization, that when you start to examine it more deeply, the world as we know it might start to unravel. Just have a look at this discussion on Stack Exchange

Only 10 years ago we thought that humans were the only species capable of symbolic thought. There is now evidence that crows, robins, prarie dogs, elephants and even domestic bees think, calculate and communicate like us in some ways.
Elephants have names for eachother. They are capable of arbitrary symbolism: the skill to assign a meaning to a speciffic symbol - a word that signifies a name.

Crows are smarter than monkeys. Crows can recognize rectangles, squares and geometric regularity. Similar to humans, they are sensitive to geometric properties such as parallel sides, symmetries and angles

Chimps can understand ratios and proportions. In image a) Sarah the chimp is presented with a glass that is half full, and two wooden disks representing 1/2 and 3/4. In image b) she chooses the correct 1/2 disk and places it beside the half full glass

All humans regardless of age, education, and culture can perceive and distinguish elementary geometric shapes. Unlike us, baboons lack these intuitions of simple geometry.

The oldest painted animal in cave art is not bison, deer or cattle. It's actually a pig. This painting is 50,200 years (+- 2,200 years) old and it's located in Indonesia. It also depicts 3 humans interacting with it.
The people that lived in Israel 23,000 years ago didn't have rectangular, nor circular bedding. Their sleeping hut had an irregular shape and their bedding was concentric or annular (ring-like), organized around the central hearth of the hut.
