Stepping outside of your comfort zone as a hunter gatherer was a lot more dangerous -- new terrains, new plants that could be poisonous, new animals that could kill you. Tipping wrong or sticking your chopsticks in your rice bowl is unlikely to lead to death or dismemberment, but it's possible our nervous system is trained to send signals that it might.
