#5 – Paranasal Sinuses
We need sinuses, but we don’t need those sinuses called paranasal sinuses that are located around our nose and under our eyes. They do nothing but bring pain to people who suffer from allergies. These sinuses get so stuffed up in people who suffer from allergies that they can barely bear the pain.
It’s believed that these sinuses once had a purpose because extra smell receptors were found in them which helped our ancestors find food better.
