Let me take a look up here.....

So, I was talking with Janey, and she told me about a PhD at her school that looks up noses. Really. And she's a neuroligist! In your nose's mucus membrane is the only place that neurons actually contact the outside world. AND (get this) in Alheimer's patients, the neurons in their noses had the same type of damage as the cells in their brains. So, next time an MD looks up your nose, (s)he could be looking for brain damage!
