i saw a grown woman pick her nose and eat it earlier . okay , so i never understood why people ate it . what is it about it that makes them want to do that ? i just flicked mine . and i thought it stopped at a child 's age . really interesting . i was so grossed out by it . i think it has to be a oral fixation or something like that . i 've heard of oral fixations before , but only in the context of like chewing fingernails and smoking cigarettes , etc . but i guess if i think about it , a lot of people chew fingernails , and i 'm sure that 's just as bad bacteria-wise . maybe the booger eaters are on to something . maybe it helps build their immune system .
The discussion about consuming bodily excretions like boogers triggered a feeling of disgust.
