Secondary shower thought, an image of Captain Caveman should be the image representing humans on the Wikipedia page.
Tertiary shower thought, we probably started wearing clothes because our own hair used to be our clothes, and we wanted to replace the hair we cut off when we started grooming.
What makes you think that people haven’t been cutting their hair since forever? Our ancestors who came before homo-sapien had cutting tools. Hair can also be burned by the fire they could also make. I’d imagine hairstyles are older than humanity.
I get “angry” (I don’t know, some emotion forces me to take action) when there is a hair in my field of view.
I’m guessing if vision is so important for modeling the world that they’d die without it, they’d do something about it (bind / cut / burn)?
Yeah. If prehistoric humanity is anything like current humanity, lots of people have been cutting their hair since time immemorial for vision and annoyance reasons alone.
Irritated, annoyed.
