Why is finding a hair in your food so disgusting? →
Yummy takeout last night wasn't appealing at all after I opened the box and there was a big long hair sitting on top of the food. It totally turned my stomach and I couldn't eat the food.
Why is this so gross? Rationally, I know that the owner of the hair is most likely a clean, decent, nice-smelling person. I know that the food was not significantly contaminated by one little hair. It did not make its way into my mouth (which is disgusting in an actual visceral way and is more understandable).
So why is it so nauseating? God, I'm getting queasy just typing this. Any strategies for preventing the psychological gross-out?
