First of all, there will be boogers because there are secretory mucosa in the nasal cavity, which can produce a lot of mucin, release it to the outside of the cell to absorb a lot of water, and its volume can expand 600 times. Mucous glands under the mucosa are constantly secreted, and the secreted water is used to moisten and inhale air. In addition, mucous glands often secrete a small amount of mucus, which is evenly distributed on the mucosal surface and absorbs dust and microorganisms inhaled in the air. When mucus catches dust or other particles in the air, it will form nasal mucus, which will dry and harden around the particles.
Because the nasal cavity has a filtering function in the immune system, air enters the lungs through the nasal cavity, and a large number of bacteria will stay in the nose. If you eat booger with a variety of bacteria and let it be absorbed by the small intestine, its effect is just like medicine, which can enhance human immunity. So eating booger every day is really healthy!
Anyway, I did eat booger when I was a child ... when I was a child, I was not sensible. When I dig my nose, I want to try it out of curiosity. Don't ask me what it tastes like, just taste it yourself. So I think I can be so healthy now, the reason must be because I ate too much booger when I was a child! That's why it's so strong!
Finally, I don't eat booger now.
