I decided to start reading this for the science stuff and a unique fl, but this insult really threw me for a loop.
Last I checked, epithelial tissue (lines your organs but also makes up your epidermis) is just a fancy word for skin. Not even the entire layer of skin, just the teeny tiny top part (epidermis). Now, last I checked, using pendulum motion to "smash" your epithelial cells honestly wouldn't even give you a bruise (those occur due to damaged capillaries; epithelial tissue isn't even vascular/containing blood vessels). Smashing your epithelial cells is the equivalent of scratching dead skin cells off... but with a pendulum instead of your nails. I'd like to see how that works.
Anyways, I might've crashed out a little more than I should've, but maybe this was just a translation error and I'm losing my mind over nothing.
Edit: guys punching someone is not pendulum motion. I’m not going to explain it here but you can search up why.
