Blood from your nose (to be precise, from a triangular region of the face centered on the nose) drains to the rear toward your brain, where it joins various other veins, including the ones that drain blood out of your brain.
If a nasal infection were to travel downstream and block this junction point (a condition known as intracranial thrombophlebitis-say that three times fast), you'd have big problems. Some doctors call it "the triangle of death."
Use a special nose hair clipper; it's a great present and a clue to a loved one.
