There is a common saying in my place: If you eat your skin, hair or nails, it will be deposited in the cecal (Vermiform) appendix, and can cause appendicitis. (This is mostly told to children to discuourge them from eating their own.)
Is there any reality in this statement? In the case of hair and nails they are dead cells, but what is the issue with skin? Skin is normally living and the cells are active.
So is there any problem digesting ones own skin?
Do nails, skin and hair must be trapped in Vermiform appendix?
