Do u even know anything abt the human body? It would be concerning if I didn't have snot/mucus, it's actually extremely hygienic, it actually helps you from not getting sick bcz the stickiness of the mucus collects dust that you breathe in and 9/10 times you're snot gathers that much dirt that it clumps up and naturally falls out - or it clings to ur nose hair which is also extremely normal - you in knowingly swallow 1-2 liters of snot/mucus per day - and ur fine - also mucus is what stops the acid in it stomach from burning thru to stomach bcz it's lined with it - and the acid in ur stomach is strong enough to melt steal
